We developed a bimanual manipulation technique to facilitate the removal of the subincisional lens cortex in small-incision phacoemulsification cataract surgery. A separate aspiration handpiece, not connected to an aspiration tube, is passed into the anterior chamber through a side-port corneal incision. Under irrigation with a standard infusion/aspiration (I/A) handpiece through a tunnel incision, the cortex is stripped off with the separate handpiece and removed with the I/A handpiece. In 227 eyes, subincisional cortex removal and subsequent capsule polishing was performed safely with the separate handpiece. Rupture of the posterior lens capsule occurred in 3 high-risk eyes.

Post-traumatic dislocation of an intraocular lens (IOL) is a serious complication, especially after a blunt trauma because the posterior chamber lenses can potentially dislocate subconjunctively. We report a case of subconjunctival dislocation of a Kelman multiflex AC IOL. Such cases require immediate wound repair with IOL explantation to prevent endophthalmitis.

A previously healthy 75-year-old woman developed blurred vision in her left eye and was found to have an amelanotic choroidal metastasis. Cranial magnetic resonance imaging disclosed 2 brain lesions compatible with metastasis. Subsequent evaluation revealed a primary cancer in the lung. Simultaneous metastasis to the choroid and the brain from an occult primary lung cancer is rare. This case underscores the need for a detailed systemic evaluation in a patient with an amelanotic choroidal mass in which a metastasis is a diagnostic consideration.

To determine annual usage and costs of laser trabeculoplasty (LTP) in the United States, we reviewed data from the Health Care Financing Administration from 1986 to 2000, using the Part B Extract and Summary System (BESS). The annual number of LTP procedures performed increased to a peak number of 176,670 in 1992 and has declined since that time, with a 57% reduction in the number of procedures performed in 2000 (75,838) compared with the peak number. The total allowed charges declined from a peak of $137,127,436 in 1991 to $27,622,073 in 2000 (80% reduction). The average allowed charge per procedure was highest in 1989 ($893), and by 2000 the average charge ($359) was reduced by 60% compared with the peak charge. The total number of LTP procedures performed in Medicare beneficiaries has decreased in recent years compared with the peak number in 1992. In recent years, there also has been a marked reduction in the total allowed charges and the average charge per procedure for LTP.

BACKGROUND AND OBJECTIVE Difficulties encountered during the repair of pseudophakic retinal detachment are related to difficulties in peripheral retinal visualization and identification of retinal breaks. The implication of nonvisualized breaks in patients with pseudophakic retinal detachment is associated with lower rates of surgical success. This report decribes the results of a prospective trial to evaluate the efficacy of both scleral buckling surgery in the treatment of pseudophakic retinal detachment with undetected retinal breaks and pars plana vitrectomy techniques in the management of the cases that redetected after primary buckling surgery. PATIENTS AND METHODS This study represents 25 cases of pseudophakic retinal detachment with undiagnosed retinal breaks. In each case, we performed a scleral buckling that extended over the circumference of the retinal detachment. Pars plana vitrectomy with internal subretinal fluid drainage and long-term tamponade were performed on 7 patients with uncomplicated recurrent retinal detachments after primary buckling surgery. The mean duration of follow up was 32 months. RESULTS There were 25 eyes (24.5%) of pseudophakic retinal detachment with undiagnosed retinal breaks represented in our pseudophakic retinal detachment cases. Anatomic success was achieved after the initial scleral buckling surgery in 18 eyes (72%). The overall success rate was 92%. The visual acuity was 20/40 or better in 8 patients (32%), 20/80 to 20/40 in 6 patients (24%), 5/200 to 20/80 in 7 patients (28%), and light perception to hand movement in 4 patients (16%). Complications included vitreous hemorrhage, macular pucker, cystoid macular edema, and hypotony with proliferative vitreoretinopathy. CONCLUSION Scleral buckling surgery in conjunction with cryotherapy is effective in the initial treatment of pseudophakic retinal detachment with undetectable retinal breaks. Pars plana vitrectomy with internal fluid-gas exchange and long-term tamponade can be used to treat these patients with recurrent retinal detachment after primary buckling surgery to get a higher overall success rate.

A 70-year-old patient with recurrent bilateral primary intraocular lymphoma (PIOL) was treated with local injections of methotrexate and periocular dexamethasone phosphate to both eyes over the course of 5 months. Local therapy consisted of a cycle to each eye of 3 intravitreal injections of methotrexate (200 microg in a total volume of 0.1 cc) administered on days 1, 5, and 8, followed by a subtenon injection of dexamethasone phosphate (7.5 mg in a total volume of 0.3 cc) on day 9. This treatment cycle was administered 4 times for the right eye and 3 times for the left eye, at 4 to 6 week intervals. Electroretinography was used to assess retinal function prior to and during each treatment regimen. Complete regression of the lymphomatous infiltrates and resolution of the vitritis was observed with preservation of visual acuity and no changes on electroretinography. The effect was sustained for 24 months after termination of treatment in the absence of systemic chemotherapy, radiation treatments, or maintenance intravitreal injections. Local combined chemotherapy can be used to treat recurrent PIOL, and can serve as successful palliative therapy in patients for whom further treatment with systemic chemotherapy or radiation is contraindicated.

BACKGROUND AND OBJECTIVES To evaluate the clinical performance of a new aspheric multifocal intraocular lens (IOL), and to compare the results with a corresponding monofocal IOL. PATIENTS AND METHODS Two groups of 20 patients each were implanted with a multifocal and monofocal IOL and prospectively studied. Distance and near vision, contrast sensitivity, depth of focus, and quality of vision were assessed in both groups. RESULTS In 85% of multifocal cases and 100% of monofocal cases, the corrected distance vision was 6/9 or better. With distance correction, 80% of multifocal cases had near vision of N9 or better against 10% of monofocal cases. The mean addition required for near vision N6 was +0.8 diopters (D) and +2.6 D in the multifocal and monofocal groups, respectively. Multifocal cases showed significantly decreased contrast sensitivity and increased depth of focus. CONCLUSIONS Multifocal IOLs are a good option for those with nonexacting visual requirements. The loss in contrast sensitivity seems to be an acceptable trade-off for satisfactory unaided near vision.

BACKGROUND AND OBJECTIVE To evaluate the effectiveness and results of pars plana vitreolensectomy approach with transscleral fixation of intraocular lens in hereditary lens subluxations. METHODS Fifteen eyes of 9 consecutive patients with a mean age of 12.8+/-6.2 years (6-26 years) with hereditary lens subluxation were operated on and the results were evaluated in a prospective study. Surgery was considered if best spectacle corrected visual acuity (BSCVA) was less than 20/70. All eyes underwent a 2-port pars plana vitreolensectomy and transscleral fixation of an intraocular lens (IOL). RESULTS The mean follow-up period was 12.6+/-7.5 months (6-22 months). There was no major intraoperative complication. Preoperatively, 8 eyes (53.3%) had a BSCVA of counting fingers (CF) and 7 eyes (46.6%) had a BSCVA of 20/200 to 20/70. Postoperatively, 14 eyes (93.3%) had a BSCVA of 20/50 or better. None of the patients had IOL decentration or intraocular pressure (IOP) increase during the follow-up period. There was a macular hole formation in 1 eye postoperatively. CONCLUSIONS The early results of pars plana vitreolensectomy with IOL implantation using scleral fixation technique had shown that it not only promises a rapid visual rehabilitation but it is also a relatively safe method. More serious complications, however, may occur in the long term.
