Descemet membrane detachments are not uncommon following cataract surgery, and large and extensive detachments can have an impressive presentation, with severe corneal edema and marked reduction in visual acuity. Traditional treatment regimens have included observation (with the hopes of spontaneous resolution), anterior chamber injections of air or viscoelastic, transcorneal suturing, and even corneal transplantation for persistent cases. During the past few years, intracameral injection with either sulfur hexafluoride (SF6) or perfluoropropane (C3F8) gas has gained increasing acceptance as an efficient and effective treatment option for Descemet membrane detachments. Previously described techniques of gas injection have required corneal and paracentesis incisions; sterile blades, cannulas, and other instruments; and occasionally, an operating room setting. We describe a simple, safe, and effective technique for intracameral gas injection that can be performed by one person at the slitlamp microscope or in a minor operating room with minimal equipment.
    • DMDs are usually small and localized to the corneal wound, with minimal or no effect on corneal clarity and vision. However, larger detachments can cause severe corneal edema and visual disturbance, and they often require surgical intervention to prevent permanent corneal decomposition and a potential corneal transplant.2-4
    [Show abstract] [Hide abstract] ABSTRACT: Descemet's membrane detachment (DMD) is an uncommon condition with a wide range of etiologies. More than likely, the most common cause is a localized detachment occurring after cataract surgery. We report three cases of Descemet's membrane detachment that occurred after uncomplicated phacoemulsification cataract surgeries. The first patient was managed without surgical intervention, the second patient was treated using an intracameral air injection, and the last patient was treated with an intracameral perfluoropropane (C3F8) gas injection. All three patients recovered their vision following the reattachment of Descemet's membrane. The three patients were treated according to the extent of the detachment.

  • [Show abstract] [Hide abstract] ABSTRACT: Z-transform approaches do not intrinsically trade off amplitude vs. frequency accuracy, as do Fourier-transform approaches. Thus, exact measurement of both quantities for the relevant harmonics is theoretically possible. However, existing Z-transform estimation methods fail in such applications because of their sensitivity to the colored, nonGaussian noise present in most inverter topologies. An approach to Z-transform estimation is presented that is very insensitive to such colored noise. The approach is developed theoretically and experimental verified on a PC-AT-based signal acquisition system using actual inverter waveforms.

  • [Show abstract] [Hide abstract] ABSTRACT: Cataract surgery has evolved dramatically over the last two decades, largely as a result of technological advances. As a result, visual outcomes and patient convalescence have improved significantly. A second consequence of increased instrumentation and technology, however, is increased complexity of cataract surgery and the advent of complications unique to these advances. Cataract surgeons must be aware and capable of managing the many possible adverse events that can occur during cataract surgery. This review identifies many of the common complications of cataract surgery, describes methods to avoid these complications and discusses techniques to address complications that do occur. It is the ability to avoid, quickly identify, and properly manage complications that defines the accomplished cataract surgeon.

  • [Show abstract] [Hide abstract] ABSTRACT: Objective:To report the preliminary results of ten consecutive cases of deep lamellar keratoplasty (DLK). Methods: Retrospective study of ten cases of DLK from December of 2003 to March of 2005 at the Suel Abujamra Institute. Seven patients (70%) presented keratoconus, one (10%) staphylococcal blepharokeratoconjunctivitis associated with rosacea, one (10%) superfitial leukoma associated with tracoma, and one case without diagnosis (10%). Biomicroscopy with and without fluorescein staining, best corrected visual acuity (BCVA), intraocular pressure, corneal topography, and specular microscopy was evaluated before and after the surgery. Four patients (40%) had dissection with viscoelastic and six (60%) with air. One case (10%) needed to be converted to penetrating keratoplasty (PK). The postoperative follow-up period varied between 7 and 21 months. Results: All cases in which DLK was completed had improved visual acuity. One patient (11%) had worsening of corneal haze, reduction of visual acuity, and edema after 10 months of follow-up. Five patients (55%) had visual acuity equal or better than 20/40, and three (33%) had visual acuity from 20/40 to 20/60. The corneal astigmatism was smaller then 5 diopters in 67% of the cases. Intra-operative complications were observed in 4 patients (44%): hyphaema after paracentesis (1 patient), microperforations (2 patients), and macroperforation of the Descemet's membrane (1 patient). Five patients (55%) had postoperative complications: lens opacity (2 patients), partial Descemet membrane detachment (2 patients), haze and stromal edema (1 patient), and paralytic mydriasis (2 patient). The average endothelial cell loss was 11%. Conclusion: DLK is a viable option for the surgical treatment of diseases that do not involve the corneal endothelium. However, a significant number of complications were observed. More prospective and comparative studies are necessary to confirm the advantages of DLK in relation to PK.

  • [Show abstract] [Hide abstract] ABSTRACT: Descemet's membrane detachment is a rare but potentially serious complication of intraocular surgery, most commonly cataract extraction. Small Descemet's membrane detachments typically resolve with topical medical therapy; however, larger detachments require surgical intervention. The most common surgical procedure is a gas-fluid exchange with 20% sulfur hexafluoride (SF6) or 14% perfluropropane (C3F8), which is typically performed at the biomicroscope and is nontoxic to the endothelium. A 77-year-old man underwent phacoemulsification with a posterior chamber lens implantation by clear corneal incision in the left eye. Visual acuity was 20/40 in the left eye 1 month postoperatively with persistent corneal edema. Visual acuity continued to deteriorate to counting fingers (CF), despite the use of topical hyperosmotics and steroids. At 2 months, a scrolled Descemet's membrane detachment was present from the incision site to the central cornea causing extensive edema. Anterior chamber injection of 14% C3F8 successfully reattached Descemet's membrane. Six weeks after surgery, the gas bubble had resolved, the central cornea was clear, and a curvilinear scar was present from 5:00 to 11:00. Visual acuity remained at CF owing to anterior capsular fibrosis. Anterior YAG capsulotomy improved the vision to 20/40. Descemet's membrane detachment can have a devastating effect on vision. Timely management is imperative to preserve vision. This case shows the successful repair of Descemet's membrane detachment with 14% C3F8 after unsuccessful topical treatment.

  • [Show abstract] [Hide abstract] ABSTRACT: Descemet's membrane detachment is a rare but serious complication following cataract surgery. Extensive detachments that affect the visual axis may result in poor vision and require penetrating corneal grafts. Some alternatives have been used to reattach Descemet's membrane: air bubble, transcorneal sutures and intracameral viscoelastic gel plus SF6 or C3F8 gas. To describe the use of non-expanding (16%) intracameral C3F8 to reattach Descemet's membrane, in six patients, following cataract surgery. The patient's mean age was 71.3 +/- 9.3. Four of the patients were females and two masculine. Immediately after the gas injection the patient was submitted to slit-lamp evaluation to verify the position of Descemet's membrane. The patients who had eyes with central or superior detachments were told to sit upright for two days. The patients whose eyes had inferior detachments were asked to lie on their back. All patients had successful reattachment of Descemet's membrane after the gas injection. We observed increase in intraocular pressure in one case. The corneal edema regressed after the second day with total resolution by the fourth day. Visual acuity improved in all cases after regression of the edema and remained stable after forty-five days. The use of non-expanding C3F8 alone for reattaching Descemet's membrane is reported for the first time in the Brazilian literature. Improvement in visual acuity is fast, the method is safe, effective and easily performed under topical anesthesia.
