A retrospective analysis of the first Indian experience on Artisan phakic intraocular lens.
ABSTRACT To evaluate the efficacy, safety, predictability and stability of implanting a polymethylmethacrylate phakic intraocular lens (PIOL) in high myopia.
A retrospective analysis of the data of patients who underwent Artisan phakic IOL implantation between 2002 and 2003 with a follow-up of at least 24 months.
An Artisan myopia lens was implanted in 60 eyes of 36 patients with preoperative myopia ranging from -5.0 to -24.0 D. Mean patient age was 22.6 years. Mean spherical equivalent of manifest refraction stabilized by the first postoperative week. At three months follow-up, 54 eyes (90%) had a postoperative refraction within +/- 1D emmetropia and 45 eyes (75%) had uncorrected visual acuity of 20/40 or better. Seven eyes (11.6%) had loss of one Snellen line and none had loss of two Snellen lines or more at three months. The mean endothelial cell loss was 3.8% at three months, 5.2% at six months, 5.25% at 12 months and 6.38% at two years, which was not significant. Postoperative complications included anterior chamber reaction in two eyes (3.3%), rise in intraocular pressure in six eyes (10%) and dislocation of PIOL in two eyes (3.3%).
Implantation of Artisan myopia lens to correct high myopia resulted in a stable and fairly predictable refractive outcome with few complications. Significant endothelial damage was not detected in two years of follow-up.

ABSTRACT: To evaluate the outcome and safety of the iris-fixated Artisan phakic intraocular lens (PIOL) for the correction of moderate and high myopia. A retrospective non-controlled clinical study of the data of patients who underwent Artisan PIOLs between March 2006 and July 2008 was evaluated. Pre-operative examination included age, gender, refraction, uncorrected (UCVA) and best spectacle corrected (BSCVA) visual acuity, predictability and safety were analyzed. Post-operative time course ranged from 12 to 36 months. An Artisan myopia lens was implanted in 62 eyes of 39 patients. The mean pre-operative spherical equivalent (SE) was -13.17 ± 5.62 D. The pre-operative myopia ranged from -4.5 to -24 D. Mean patient age was 25.44 ± 5.22 years. At last follow-up visit, residual SE was within ±1.00 D in 36 eyes (58.1%) and ±2.00 D in 56 eyes (90.3%). In the last visit UCVA was equal to or better than pre-operative BSCVA in 57 (91.9%) of the eyes. One eye (1.6%) lost one Snellen line, three eyes (4.8%) lost two or more Snellen lines and one eye lost vision (1.6%). Post-operative complications included anterior chamber reaction in one eye, rise in intraocular pressure in two eyes and retinal detachment in one eye. When laser keratorefractive surgery is not an option, implantation of Artisan PIOL to correct moderate to high myopia results in a stable and good refractive result with few complications that must be kept in mind.Oman Journal of Ophthalmology 09/2012; 5(3):175-80.

ABSTRACT: Many factors are involved in choosing which approach is best for each patient. By Mayank a. nanavaty, DO, MRCS(ED), FRCOphth; and Sheraz M. Daya, MD, FACp, FACS, FRCS(ED), FRCOphth decision-Making: rLe versus phakic ioLs Refractive lens exchange (RLE) and phakic IOL implantation are alternative options to laser ablative refractive surgery. As intraocular procedures, both carry the very low but real risk of endophthalmitis. This risk has been reduced considerably by the incorporation of intraocular cefuroxime into current practice in Europe. 1 Although rare, potential complications including retinal detachment and cystoid macular edema must be considered and discussed with a patient in detail before surgery. UnderStanding RLE and Phakic iOLS RLE is safe and effective for the correction of moderate to severe myopia 2-7 and hyperopia. 8-13 Monofocal, toric, multifo-cal, and accommodating IOLs are available options that can be chosen based on patient needs and expectations. The safety of the procedure has been enhanced by the introduction of microincision cataract surgery (MICS) and of lenses that can be inserted through 1.8-mm incisions. Because RLE causes loss of accommodation, the procedure should be avoided if a patient's natural lens is still functional. 14-18 Several available multifocal IOLs provide patients with increased depth of focus including near, intermediate, and distance vision and make RLE an attractive option for both patient and surgeon. The primary advantages of phakic IOLs are rapid visual recovery, reversibility, a broader range of treatable ametropia, high predictability rates, stability, and preservation of accommodation. 19-2710/2012;
