ABSTRACT: Comparison of subjective evaluation of patients with low and moderate myopia undergoing photorefractive keratectomy (PRK) and Laser in Situ Keratomileusis (LASIK) on two types of excimer lasers: Schwind Esiris and Schwind Amaris.
Patients were divided into two groups according to the type of laser that was used. Group A comprised of 23 patients (14 females, 9 males) of average age 33.1 years (range 21-51 years), with an average spherical equivalent before operation of -3.5D. Using the excimer laser Esiris (Schwind, Germany), 10 patients had undergone PRK and 13 LASIK. Group B comprised of 32 patients (21 females, 11 males), of average age 31.9 years (range 22-48 years). Median spherical equivalent before operation was -3.05D. With the excimer laser Amaris (Schwind, Germany) 17 patients had undergone PRK and 15 LASIK. For the subjective evaluation we set up a questioner consisting of 21 questions that were aimed on the quality of vision under various illumination types and intensities, vision under various distances, activities and also questions concerning superficial sensitivity of the anterior segment of the eye.
We detected a 100% satisfaction one year after refractive laser treatment with both laser types. Statistical improvement was evident by one month after treatment in both patient groups and upto 12 months it progressively increased. Statistically significant differences were noted one month after treatment, where patients in group B were more satisfied in questions concerning quality of vision, distance vision, while watching TV and driving during daytime and during the night. During further follow-up, results were comparable between both groups.
Temporary patient satisfaction treated with laser Amaris is apparently due to the result of a more sparing treatment and thus fewer changes in the corneal stroma.

ABSTRACT: To assess the effect of the cleaning of the posterior capsule using pulses of balanced salt solution (BSS) on the corneal endothelial cells.
This pilot study involves 43 patients with bilateral cataracts having lens removal using torsional phacoemulsification (Ozil, Infiniti, Alcon) and bimanul irrigation/aspiration (I/A). Posterior capsule of the right eye of each patient was cleaned using pulses of BSS (AquaLase, Infiniti, Alcon). Surgery was performed by one of 2 surgeons (NJ, PR), both eyes of each patient was operated on by the same surgeon. Best corrected visual acuity (BCVA), endotelial cell count and pachymetry were evaluated pre- and postoperatively as well as occurence af peri- and postoperative complications.
Preoperative mean pachymetry (P) was 566 +/- 45 microm in the right eye (RE) and 562 +/- 42 microm in the left eye (LE), mean endotelial cell count (ECC) 2541 +/- 317 cells/mm2 (RE) and 2567 +/- 311 cells/mm2 (LE). Three months after surgery P was 557 +/- 43 microm (RE) and 558 +/- 45 microm (LE) and ECC 2368 +/- 416 cells/mm2 (RE) and 2396 +/- 417 cells/mm2 (LE). There was no statistical difference in postoperative changes of both corneal parameters between right and left eyes. Best corrected visual acuity improved in all eyes and no peri-or postoperative complications occured.
Cleaning of the posterior capsule using AquaLase is safe for corneal endothelial cells.

ABSTRACT: To evaluate and compare posterior capsule opacification (PCO) incidence and the best-corrected visual acuity (BCVA) in patients who underwent the implantation of intraocular lens (IOL) made of polymethylmethacrylate (PMMA), or hydrophobic acrylic material, or silicone material. All patients were examined 7 years after the surgery at the Department of Ophthalmology, University Hospital, Hradec Králové, Czech Republic, E.U.
In this 60 study, sixty eyes (44 patients) were evaluated; 20 eyes with IOLs made of PMMA with round edge, 20 eyes with IOLs made of hydrophobic acrylic material with square edge and 20 eyes with IOLs made of silicone material with round edge. They were examined 7 years after surgery. The eyes treated with Nd:YAG laser capsulotomy were excluded from the EPCO 2000 evaluation. The EPCO 2000 software (Evaluation of Posterior Capsule Opacification) was used for PCO assessment. The density of the opacification was graded clinically from 1 to 4. The BCVA, the PCO index for every PCO grade and total PCO index were compared.
Mean of total PCO index for PMMA IOLs was 0.451 +/- 0.619; for hydrophobic acrylic IOLs 0.361 +/- 0.397; and for silicone IOLs 0.552 +/- 0.372. During the examination, we have found the BCVA mean to be for PMMA IOLs 0.79 +/- 0.26, for hydrophobic acrylic IOLs 0.87 +/- 0.19, and silicone IOLs 0.78 +/- 0.29 respectively. Twenty eyes of twenty patients required Nd:YAG laser capsulotomy: twelve eyes with PMMA IOLs, two eyes with hydrophobic acrylic IOLs, and six eyes with silicone IOLs.
In this study, the difference in PCO incidence and BCVA among PMMA, hydrophobic acrylic, and silicone IOLs were not statistically significant. The highest incidence of the Nd:YAG laser capsulotomy was in the group of PMMA IOLs, then in silicone IOLs, and the lowest incidence was in the group of hydrophobic acrylic IOLs.

ABSTRACT: To compare the results of the microbiological examination of aqueous humor after implantation of the intraocular lens (IOL) CORNEAL using either injector or forceps.
In this prospective randomized clinical study 46 eyes (43 patients) were implanted with the hydrophylic acrylic IOL CORNEAL ACR6D SE. Injector was used in 23 eyes and folding and implantation forceps in 23 eyes. After delivery of the IOL in the capsular bag, viscoelastic material was removed using bimanual I/A and the specimen for microbiological examination was obtained. The anterior chamber was filled with balanced salt solution, intracameral antibiotics were injected and the stroma alongside the primary incision and the side port incisions were lightly irrigated to form a fairly secure seal.
The results of primary cultivation were negative in all specimen. Only threetimes sporadic colonies of Staphylococcus plasmacoag. neg. were isolated from the liquid medium after reincubation, that were described by microbiologist as very probably contamination of the sample. At two from these three cases forceps were used for implantation, once injector. Anaerobic and mycologic examinations of all samples were negative. There was no evidence of postoperative inflammation in any case.
Both implantation techniques proved to be safe with no significant differences comparing the microbiological examination and postoperative outcome.

ABSTRACT: To compare the degree of posterior capsule opacification (PCO) after cataract surgery in patients with type 2 diabetes mellitus (DM) and in nondiabetic patients.
All surgeries were done at Department of Ophthalmology, University Hospital in Hradec Králové and three-piece Alcon AcrySof intraocular lens (MA60BM or MA30BA) was implanted in all eyes. Seven years after surgery, examination of eyes was done including best corrected Snellen visual acuity (BCVA) measurement. Digital retroillumination photographs of mydriatic anterior segments were taken and PCO was assessed using EPCO 2000 software for PCO quantification. Patients enrolled in the study were devided into two groups--with type 2 DM and without DM. EPCO index for 4 PCO severity grades and Total EPCO index for entire IOL were compared between the groups. The incidence of Nd:YAG laser capsulotomy and operative Elschnigg pearls removal, as well as BCVA, were also evaluated. Statistical analysis was performed using nonparametric tests.
82 patients (140 eyes) were analyzed. 26 of them (36 eyes) were type 2 diabetics (DM group), none type 1 diabetics, remaining 56 nondiabetic patients (104 eyes) were enrolled in the control group. Total EPCO index for the DM group was 0.531 +/- 0.543, for the control group 0.492 +/- 0.532, no significant difference (P = 0.66). No significant different in Nd:YAG capsulotomy rate (22.2% for DM vs. 17.3% for control, P = 0.62) and operative Elschnigg pearls removal (8.3% for DM vs. 1.9% for control, P = 0.11) was proved. BCVA in the DM group was 0.80 +/- 0.29, in the control group 0.82 +/- 0.22, no significant difference (P = 0.78).
No significant difference in PCO extent, Nd:YAG capsulotomy rate and operative PCO treatment was proved between the patients with type 2 DM and the control group. However, all outcomes were nonsignificantly worse in the diabetic patients.

ABSTRACT: To assess postoperative outcomes of implanted hydrophilic expandable intraocular lenses ACQUA.
One hundred eyes of 75 patients with implanted intraocular lens (IOL) ACQUA were involved. IOLs were implanted during the period 2004 to 2005. The uncorrected visual acuity (UCVA) and the best-corrected visual acuity (BCVA), refractive error and its spherical equivalent (SE) were measured preoperatively and 1 day, 1, 6, 12 months postoperatively. Possible postoperative complications were evaluated as well. The patients were divided into two groups: first group with the age-related macular degeneration (ARMD) and the second one without it.
Sixty-five patients (90 eyes) finished the one-year follow-up period. Preoperative UCVA was 0.23 +/- 0.19, BCVA 0.43 +/- 0.23 and SE + 0.15 +/- + 2.06 D (dioptres). Statistically significant differences between UCVA and BCVA one day and one month postoperatively were established. Six months after the operation and later on, the mean UCVA and BCVA were 0.61 +/- 0.26, and 0.82 +/- 0.23 respectively in all eyes, and 0.67 +/- 0.24, and 0.9 +/- 0.17 respectively in the group of eyes without ARMD. Spherical equivalent was stable during the whole follow-up period, one year after the surgery it was -0.1 +/- 1.12 D in the group of all 90 eyes. The IOL central positioning in the bag was excellent in 86 eyes. Nd:YAG laser anterior capsulotomies were performed in two eyes due to the stricture of the anterior capsule and posterior capsulotomy was performed in one eye due to the fibrous secondary cataract. The ACQUA IOL had to be explanted from one eye because of recurrent acute non-infectious inflammation of the anterior segment.
According to our experience, the IOL ACQUA Mediphacos shows good and stable postoperative outcomes.

ABSTRACT: Our objective was to evaluate the postoperative outcomes of the surgical treatment for recurrent pterygia. Twelve eyes of 10 patients operated on for recurrent pterygia at the Department of Ophthalmology, University Hospital Hradec Kralove, Czech Republic, were involved in this study. All surgeries were done under the local anesthesia. The pterygium head was undermined and removed by dissection to reach the clear corneal lamelae. The pterygium body was thoroughly removed with extensive dissection of scared pathological tissue. In 3 eyes, the Mitomycin C 0.004% solution was applied. Preserved human amniotic membrane was placed over the corneal and conjunctival defects and sutured with 8/0 Vicryl interrupted sutures. Postoperative results were good; in 11 eyes we did not observe the true corneal recurrence of fibrovascular tissue. In one eye only, the lamellar sclerokeratoplasty was necessary to perform because of the recurrence of pterygium. Recurrent pterygium exhibits a more aggressive, fibrovascular growth pattern, leading to the corneal and conjunctival scarring and limbal stem cells deficiency. Proper excision of pathological tissue with amniotic membrane transplantation and/or Mitomycin C represents an alternative surgical method with good final outcomes.

ABSTRACT: The authors present results of retrospective study of 10 cases of Aqua-Sense hydrophilic acrylic intraocular lens (IOL) explantation performed during the calendar year 2005 at the Department of Ophthalmology, University Hospital, Hradec Králové, Czech Republic. The preoperative visual functions, perioperative findings and postoperative results were evaluated. The best corrected visual acuity (BCVA) before explantation was surprisingly good, even in cases with severe opacification of the lens. There were no serious perioperative complications; in 9 cases, the stable capsular bag enabled us to implant the new IOL in the bag or in the sulcus. In one case, the suction of the secondary cataract was done. In one eye, the zonular dehiscence developed, and the new IOL was placed into the anterior chamber (angle supported AC IOL). We did not see any postoperative complications. The BCVA improved in 3 eyes, in 7 eyes the BCVA remained the same. All patients were satisfied with the postoperative results. Histopathological examinations of the explanted IOLs showed multiple tiny calcium granules concentrated in continuous narrow band closely beneath the anterior surface of the optic part of the IOL. The postoperative calcification of some currently available hydrophilic acrylic IOLs is one of the common reasons for IOL explantation/exchange. Sophisticated surgical techniques greatly improved the postoperative results.

ABSTRACT: The authors refer about the results of the secondary implantation of the anterior chamber intraocular lens (AC IOL) Artisan Aphakia. Those specially constructed iris claw lenses for aphakia correction, fixated on the iris, were implanted at the Department of Ophthalmology in Hradec Králové (Königgrätz, Czech Republic) during the period August 2002-May 2005 in 51 cases (51 eyes, 48 patients). The most common indication (33 % of cases) was the previous trauma with lens damage and consequent postoperative aphakia. The second most common cause (in 29 %) of AC IOL use was the absence of the lens after the posterior segment surgery due to the retinal detachment. In 18 % of cases the aphakia was as a result of the complicated intracapsular or extracapsular cataract extraction. The other indications (20 %) for the AC IOL implantation are patients with subluxated their own (natural) lens in Marfan's syndrome; after posterior segment surgery due to the intravitreal hemorrhage with primary cataract extraction without the IOL implantation; and after the luxation of the artificial intraocular lens or the lens remnants as a primary complication after the cataract surgery. The average patients' age at the time of surgery was 59 years (range, 8-86 years). Men participated in 70.6 % of cases. In the group of patients, there was one child as well. Before the surgery, the average spherical refractive error was +9.8 +/- 2.2 diopters (D) (range, 3-15 D), the average uncorrected visual acuity was 0.05 +/- 0.09; the best-corrected visual acuity was 0.42 +/- 0.29. No complication during the surgeries was noticed. The followed parameters were visual acuity, refraction, AC IOL position, and occurrence of complications. The average follow-up period was 13.0 months (range, 2-30 months). After the surgery, the average spherical refraction decreased to -0.5 +/- 1.62 D. The uncorrected visual acuity was 0.27 +/- 0.23 and the best-corrected visual acuity was 0.43 +/- 0.28. As complications, we noticed the secondary glaucoma in three cases, in two cases bleeding into the anterior chamber, in 5 cases iritis, and in one case the subluxation of the artificial lens.

ABSTRACT: The authors refer about highly effective and in our ophthalmology not yet described method of surgical treatment of complicated cataract in patients with high degree of preexisting astigmatism over 3.0 cylindrical diopters. According to the etiology of astigmatism, in the group, there are patients with cataract and high ametropia after previous corneal transplantation and patients with cataract and preexisting high ametropia without any previous surgery. The referred group consists of 14 patients (19 eyes), and 9 of them (9 eyes) underwent in the past penetrating keratoplasty (PK) due to keratoconus at our department. The common sign of this subgroup was unsatisfactory postoperative refraction and later on the progressive cataract development. The other part of the group consisted of 5 patients (5 eyes) and they underwent no surgery in the past. For the surgical treatment of cataract and astigmatism at once we have used the individually manufactured silicone toric intraocular lens made by the company Human Optics (type MS 6116 TU). The average age of the whole group at the time of the cataract surgery was 51.5 +/- 6.8 years (range, 39-66 years). The group consisted of 8 women (57.1%) and 6 men (42.9%). The average duration of the period between the keratoplasty and the cataract surgery was 4.8 +/- 3.6 years. The uncorrected visual acuity before the cataract surgery was 0.10 +/- 0.11, and the best-corrected visual acuity was 0.39 +/- 0.22. The average value of the preoperative refractive error was +3.4 +/- 5.0 dioptres (range, -11.0 to +10.0 dioptres) and -6.4 +/- 2.3 cylindrical dioptres (range, -12.0 to -3.0 cylindical dioptres). The average follow up period was 9.6 months (range, 4-18 months). In the postoperative period we noticed improving of the uncorrected visual acuity to the value 0.50 +/- 0.26, and the best-corrected visual acuity improved finally to 0.56 +/- 0.26. The final average refractive error decreased to 0.44 +/- 0.86 dioptres and -1.8 +/- 0.77 cylindrical dioptres.

ABSTRACT: To retrospectively evaluate postoperative outcomes and intraoperative and postoperative complications of clear lens extraction (CLE) with posterior chamber intraocular lens (IOL) implantation for high refractive errors.
Sixty five (65) patients (129 eyes) who had undergone CLE with posterior chamber IOL implantation from 6/1999-6/2001. We chosen this method for all patients after exclusion of other methods of refractive surgery. The mean follow-up in all patients was 23,2 months (range 24 to 36 months). Eyes were divided into group A (myopia) with 13 patients (5 men, 8 women), average age 44.76 years (range 25 to 66 years) and group B (hyperopia) with 52 patients (24 men, 28 women), average age 49.47 years (range 27 to 64 years).
Group A. The mean preoperative spherical equivalent refraction was -11.05 +/- 3.56 Dsf (range -15.5 Dsf do -3.5 Dsf), the mean postoperative spherical equivalent refraction was -1.17 +/- 1.04 Dsf (range -2.75 Dsf do 0 Dsf). The mean preoperative uncorrected visual acuity (UCVA) (decimal equivalent) was 0.02 +/- 0.009, the mean postoperative UCVA was 0.34 +/- 0.26. The mean preoperative best-corrected visual acuity BCVA was 0.57 +/- 0.32, the mean postoperative BCVA 0.65 +/- 0.24. Group B. The mean preoperative spherical equivalent refrection was +5.36 +/- 2.21 Dsf (range +2.00 Dsf to +13.0 Dsf). The mean postoperative spherical equivalent refraction was +0,0 7 +/- 0.89 Dsf (range -1,5 Dsf do + 4.5 Dsf). The mean preoperative uncorrected visual acuity (UCVA) was 0.13 +/- 0.12, the mean postoperative UCVA was 0.53 +/- 0.23. The mean preoperative best-corrected visual acuity BCVA was 0.76 +/- 0.28, the mean postoperative BCVA 0.69 +/- 0.27. No significant complications were observed.
Refractive lensectomy with posterior chamber IOL implantation is safe, predictable, and effective. RL can achieve excellent visual acuity and refractive outcome with few complications.

ABSTRACT: To compare posterior capsule opacification (PCO) incidence and the best corrected visual acuity (BCVA) in patients who had the soft intraocular lens (IOL) made of hydrophobic acrylic material (AcrySof MA30BA, MA60BM) implanted in their one eye and IOL made of silicone material (Allergan SI-30NB) implanted in their second eye. All patients included in this study were operated on at Department of Ophthalmology, University Hospital, Hradec Králové, Czech Republic during the period from 1999 to 2002.
Twenty-four patients (8 males, 21 females) were included in this study; they were 3 to 6 years after surgery (median 5 years). The EPCO 2000 software (The Evaluation of Posterior Capsule Opacification) was used for PCO assessment. Eyes treated with Nd: YAG laser capsulotomy were excluded from EPCO 2000 evaluation. The density of the opacification was graded clinically from 1 to 4. We compared BCVA, PCO index for every PCO grade and total PCO index.
Seven eyes of five patients required Nd: YAG laser capsulotomy, 2 eyes with AcrySof IOL, 5 eyes with Allergan IOL. Median of total PCO index for 48 eyes of 24 patients was for AcrySof IOL 0.496 vs. 0.315 for Allergan IOL. On the evaluation, median of BCVA was for AcrySof IOL 1.0 vs. 0.67 for Allergan IOL.
The difference in PCO incidence and BCVA between the silicone and the soft acrylic IOLs were not conclusive in this study. But Nd: YAG laser capsulotomy incidence was higher in the silicone IOLs.

ABSTRACT: The authors refer about their experience with the surgical correction of the presbyopia by means of the Prelex (presbyopic lens exchange) method. Patients, who underwent this type of refractive surgery procedure to decrease their dependency on glasses correction for far as well as for near vision (12 patients, 23 eyes) and 1 young female patient (2 eyes) with juvenile cataract and high hyperopia, were included in the study. The average age at the time of the surgery was 51.0 +/- 5.5 years (range, 19-77 years). The average follow up period of the whole group of patients is 9.8 months (range, 1-13 months). Depending on the type of the lens implanted, the group was divided into subgroup A with the accommodative lens 1 CU produced by Human Optics Company implanted, and subgroup B with the accommodative lens Kellan TetraFlex KH 3500 produced by LensTec Company implanted. The subgroup A consists of 8 patients (15 eyes) with the average preoperative refractive error +2.35 +/- 3.45 diopters. The average uncorrected visual acuity of this group was 0.24 +/- 0.18, and the average best-corrected visual acuity was 0.77 +/- 0.22 at the time before the surgery. The average glasses correction for near was +4.1 dioptres, and the uncorrected vision for near was Jaeger's table Nr. (J) 13. The B subgroup consists of 5 patients (10 eyes). The average preoperative refractive error was +2.23 +/- 0.93 diopters. The average value of the uncorrected visual acuity before the surgery was 0.43 +/- 0.28, and the average corrected visual acuity was 0.82 +/- 0.25. The average value of the glasses correction for near was +5.25 and uncorrected vision for near J 13. The final average postoperative error at the time of the last visit was in the A subgroup +0.06 +/- 1.17 dioptres. The average uncorrected visual acuity was 0.69 +/- 0.24, and the average best-corrected visual acuity 0.96 +/- 0.12. The average vision of the patients of this subgroup for near was J 3. In the B subgroup we found at the last visit the average final value of the postoperative refractive error -0.2 +/- 0.72 dioptres. The average uncorrected visual acuity 0.57 +/- 0.22 and the average corrected visual acuity 0.95 +/- 0.12. Average uncorrected vision for near was J 5. We did not notice any serious per- or postoperative complication of this procedure.

ABSTRACT: Authors present the possibilities of extensive submacular hemorrhage surgery in a patient after serious eye injury with bleeding into the vitreous and underneath the retina. The combination of vitrectomy with tissue plasminogen activator application into the subretinal space allows better to dissolve the coagulated blood and facilitates its removal. This procedure with correct operation technique decreases the damage of the retinal tissue and consequently preserves the photoreceptors' function. In this report, a result of surgical treatment in a 22-year-old man is presented. In the presence of intravitreal bleeding and submacular hemorrhage, during the vitrectomy the tissue plasminogen activator was used, which during few minutes dissolved the already coagulated hemorrhage and facilitated its whole removal from the subretinal space.

ABSTRACT: The authors present a case of vernal keratoconjunctivitis (VKC) in 5 years old boy. Despite intensive topical pharmacological therapy (mast-cell stabilizers, antihistamines, steroids in acute exacerbations) unsatisfied reduction of the symptoms was observed and cornea became involved in the left eye (LE). Repeated surgical abrasion of the papillary hypertrophy was performed with temporaly relief. We decided to provide a cryocoagulation of the papillary hypertrophy in the LE. We did not see any pre and post operative complications, significant improvement was observed and the patient is now (13 months after the surgery) in a good condition, on mast cell stabilizers only.

ABSTRACT: The implantation of the intraocular anterior chamber phakic toric lens (PTIOL) Artisan, a product of the Ophtec company, is one of the most up-to-date methods of the correction of higher degree of myopic as well as hyperopic astigmatism. The authors refer about the results of PTIOL Artisan implantation in 6 patients (10 eyes). The major indication was the hyperopic astigmatism--in 5 patients (8 eyes); in one patient the indication was myopic astigmatism. In the followed up group of patients, there is the preponderance of men (5), and one woman only. The patients were divided into two subgroups: one with myopic astigmatism (1 patient, 2 eyes) and other with hyperopic astigmatism (5 patients, 8 eyes). The average age of the whole group at the time of the surgery was 27.7 +/- 2.8 years (range 23-38 years) and the average follow up period was 13.0 +/- 6.9 months (range 6-22 months). In the group the patients with follow up period shorter than 6 months were not included. The average preoperative spherical refractive error was +4.8 +/- 2.25 dioptres (D) and the average astigmatic error was -5.15 +/- 2.82 cylinders (Dcyl). In one case of myopia, the preoperative refractive error in both eyes was -7.0 D and -3.5 Dcyl. The target refraction was emetropia +/- 1.0 D. The authors evaluate the final uncorrected and best-corrected visual acuity (UCVA, BCVA), final postoperative refractive error, presence of intra- as well as postoperative complications, and changes of endothelial cells' density over time. The average final postoperative error in patients with hyperopic astigmatism was +0.72 +/- 0.93 D and -1.08 +/- 0.60 Dcyl. In the only patient with myopic astigmatism the final postoperative error of both eyes was +0.5 D and -0.5 Dcyl. The advantage of the PTIOL implantation is fast visual recovery, potential reversibility of the procedure, maintaining of the accommodation, and stability of the postoperative refraction.

ABSTRACT: Standard ERG examinations were performed in 61 patients with ARMD before and after radiotherapy. Before the radiotherapy, a significant decrease in the cone b- wave amplitude and a significant reduction of the sum of oscillatory potentials (OP1-OP4) were found. At 24 months after the first dose of radiotherapy, a significant decrease in the rod response and 30-Hz flicker response were described. A possible explanation for the findings is an influence of radiotherapy onto primary circulatory disturbances in the whole retina in ARMD.
