Combined cataract extraction and trabeculectomy: phacoemulsification compared with extracapsular technique.

Thirty-four eyes undergoing phacoemulsification and trabeculectomy (PHACO + TRAB) were followed prospectively for 1 year postoperatively. The results of surgery were compared with those, obtained retrospectively, of the previous 34 extracapsular cataract extractions with trabeculectomy (ECCE + TRAB) performed by the same surgical team. All eyes received posterior chamber intraocular lens implants. Preoperatively, the two groups did not differ significantly in terms of age, gender distribution, or degree and duration of glaucoma and cataract. Mean postoperative follow up for the ECCE+TRAB group was 13.6 months; for the PHACO + TRAB group, 12.6 months (P = .1). As compared with the ECCE + TRAB group, the PHACO + TRAB group had earlier visual rehabilitation, less postoperative astigmatism (P < .001), and improved long-term intraocular pressure control (P = .04). Early postoperative pressure spikes occurred in 32% of the ECCE + TRAB eyes and in 23.5% of the PHACO + TRAB eyes (P = .2). Other postoperative complications occurred more commonly in the ECCE + TRAB group: hyphema (P < .001), fibrinous iritis (P < .01), choroidal detachment (P < .05), and hypotony (P < .05). Posterior capsular opacification was significantly more common in the ECCE + TRAB group (P < .02). These major differences probably are attributable primarily to the small incision used in phacoemulsification, which is associated with sustained IOP control during the operation, a small stable wound with low postoperative astigmatism, and early stabilization of refraction.

Effect of intracameral carbachol on intraocular pressure after cataract extraction.

Thirty-two patients were randomly assigned to a treatment or a control group to determine the dose-response and duration of action of intracameral carbachol on immediate postoperative intraocular pressure after extracapsular cataract extraction using a viscoelastic substance. Patients in the treatment group received 0.5, 0.25, or 0.1 ml of 0.01% intracameral carbachol. Patients in the control group received 0.1 or 0.5 ml of balanced salt solution. Intraocular pressures of all patients were measured preoperatively and at three, six, 12, 24, and 48 hours postoperatively. The control group as a whole showed a 9.5-mm Hg intraocular pressure rise at three hours, a 10.0-mm Hg rise at six hours, a 9.0-mm Hg rise at 12 hours, and a 7.2-mm Hg rise at 24 hours postoperatively. The group treated with 0.5 ml of carbachol maintained stable intraocular pressures through the 48-hour measurement period. The groups treated with 0.25 and 0.1 ml of carbachol maintained stable intraocular pressures through 24 hours postoperatively. The differences in intraocular pressure were statistically significant for all treated groups through the 24-hour measurement.

[Pseudo-exfoliation syndrome with and without glaucoma as a major risk factor in extracapsular cataract extraction. A prospective clinical study].

A prospective study was undertaken to evaluate the risk factors in extracapsular surgery for eyes with pseudoexfoliation syndrome (PES) with and without open angle glaucoma. The study included 3095 planned extracapsular cataract extractions performed by 18 surgeons between September 1986 and June 1989. Of the 3095 eyes 153 (4.9%) showed clinical signs of PES. We examined three groups of eyes: nonglaucomatous eyes (2476 eyes), glaucomatous eyes controlled by local antiglaucomatous therapy (342 eyes) and glaucomatous eyes that had undergone antiglaucomatous surgery (277 eyes). For each group, the incidence of capsular breaks and vitreous loss was evaluated for eyes with and without PES. In the group of nonglaucomatous eyes, vitreous loss occurred significantly more frequently (p less than 0.05) in eyes with PES. For the group of glaucomatous eyes, complications were more frequent but not significant in the presence of PES (p greater than 0.15). We conclude that PES is a significant risk factor in extracapsular surgery even in the absence of glaucoma. After introducing special precautionary measures for eyes showing signs of PES, the incidence of complications in extracapsular surgery has decreased considerably in our hospital for these eyes.

Extracapsular cataract extraction and posterior chamber lens implantation in patients with primary chronic angle-closure glaucoma: effect on intraocular pressure control.

Twenty-three eyes of 22 consecutive patients with primary chronic angle-closure glaucoma (PCACG) undergoing extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation were studied prospectively to assess the effect of ECCE on intraocular pressure (IOP) control. For comparison, a group of 21 eyes with open angle glaucoma (OAG) which had undergone ECCE were reviewed retrospectively. The PCACG group had a low incidence of acute post-operative IOP elevations (9%), and long-term the majority (65%) achieved an IOP less than 21 mmHg off all glaucoma medications. In the OAG group the IOP control was largely unaffected. We recommend that eyes with cataract and PCACG should be considered for ECCE as a first procedure rather than combined cataract and filtering surgery.

[Diagonal incision in capsulotomy for extracapsular cataract extraction].

From previous experience with all current surgery methods and kinds of anterior capsulotomy as well as of 6-year follow-up observation we developed our own diagonally-shaped (linear) capsulotomy technique. This technique was used in more than 500 successive extracapsular cataract extractions, followed by implantation of a posterior chamber lens. Both, intraoperative advantages and postoperative positive experience, will now be described.

Ketorolac treatment of pseudophakic cystoid macular edema identified more than 24 months after cataract extraction.

OBJECTIVE: To evaluate whether ketorolac ophthalmic drops prescribed four times a day can be associated with improved visual acuity and prompt resolution of edema for patients with pseudophakic cystoid macular edema identified more than 24 months after cataract surgery. DESIGN: Prospective, nonrandomized, comparative (subject self-controlled) trial. PARTICIPANTS: The records of nine patients who had pseudophakic cystoid macular edema more than 24 months after cataract surgery at the time treatment commenced were identified at the Wilmer Retinal Vascular Center from September 1, 1996, through March 1, 1997. MAIN OUTCOME MEASURES: Best-corrected visual acuities measured on a retroilluminated Bailey-Lovie chart approximately every 3 months, contact lens biomicroscopy, and fluorescein angiography following ketorolac. INTERVENTION: Commercially available ketorolac ophthalmic drops 0.5% were prescribed for the affected eye four times a day for at least 3 months and continued until edema resolved. RESULTS: Ten eyes of nine patients were identified more than 24 months after cataract extraction (median, 59 months). Seven eyes (70%) improved (mean, +3.2 lines; range, +1 to +13 lines), including six by 2 or more lines 3 months after treatment initiation. Two eyes (20%) were unchanged, and one eye (10%) was 1 line worse. All seven eyes that improved 1 line or more had some or complete angiographic resolution of fluorescein dye leakage. In these seven eyes, ketorolac was discontinued when dye leakage completely resolved or failed to continue to improve on periodic 3-month follow-up examinations. In all seven eyes, recurrence of edema was noted within 3 months after ketorolac was stopped. CONCLUSIONS: Chronic pseudophakic cystoid macular edema identified more than 24 months after cataract surgery can improve with topical ketorolac but probably requires persistent use.

[Incidence of cystoid macular edema following cataract extraction].

In a prospective study we research the incidence of cystoid macular edema following intracapsular cataract extraction with the Choyce-Mark-IX implantation method. The only eyes included in the study were those for which the operation had been uncomplicated. Fluorescence angiography was performed after 8 days, 6 weeks, 6 months and 1 year. The edema was graded accordingly: grades I-III. Cystoid macular edema of grade III was demonstrated in 4% after 6 weeks but not after 6 months and 1 year. After 1 year, grade II occurred in 2% and grade I in 15%, respectively. Visual acuity, however, was not impaired.

[Pseudo-exfoliation syndrome as a risk factor for vitreous loss in extra-capsular cataract extraction. The Erlangen Eye Information Group].

A prospective study for evaluation of the pseudoexfoliation syndrome (PES) as a risk factor in extracapsular surgery was undertaken from February 1986 to June 1988. The study included 2042 planned extracapsular cataract extractions performed by 12 surgeons. Seventy-two eyes revealed PES (3.5%). Frequency of PES increased with age (p less than 0.005). The male-female ratio of PES was 1:1.6, and eyes of average axial length showed PES more frequently than myopic or hyperopic eyes, although these differences were not significant statistically. The incidence of vitreous loss was 11.1% in eyes with PES and 1.6% in eyes without PES, a sevenfold increase that was statistically significant (p less than 0.0001). Rupture of the posterior lens capsule was observed in 4.2% of PES eyes compared to 2.8% of eyes without PES (no significance). The pseudoexfoliation syndrome is not a harmless anomaly, but a potentially disastrous disease of the anterior segment of the eye. As precautionary measures we recommend thorough biomicroscopic examination preoperatively for signs of PES, iridotomy or sector iridectomy in cases with poorly dilating pupils, very gentle manipulation intraoperatively, and posterior chamber lens sulcus implantation in eyes with zonular defects or phacodonesis.

Efficacy of diclofenac sodium ophthalmic solution versus placebo in reducing inflammation following cataract extraction and posterior chamber lens implantation.

One hundred forty-eight patients were enrolled in a randomized, prospective, placebo-controlled clinical trial evaluating the efficacy of diclofenac sodium (Voltaren Ophthalmic) in reducing ocular inflammation following extracapsular cataract extraction with posterior chamber intraocular lens implantation. Eligible patients were enrolled and randomized (2:1 diclofenac:placebo) if the sum of anterior chamber cells plus flare one day postoperatively (baseline) was at least four. None of the patients received concomitant steroidal anti-inflammatory treatment. The 99 patients receiving diclofenac sodium had significantly greater improvement from baseline in summed flare plus cell score than the 49 placebo patients at two to five days and seven to nine days after baseline. Similarly, diclofenac sodium patients had significantly less post-baseline conjunctival erythema and ciliary flush than placebo patients. Significantly more diclofenac sodium patients than placebo patients showed moderate to marked improvement from baseline in overall assessment of inflammatory response. Forty-nine percent of placebo patients but only 17% of diclofenac patients were considered therapeutic failures (P < .001). By five to seven days, 82% of diclofenac sodium patients and 59% of placebo patients had corrected visual acuities of 20/40 or better (P < .001). There were no clinically important differences in mean intraocular pressure at any visit.

Extracapsular cataract extraction and posterior chamber intraocular lens implantation in uveitis patients.

PURPOSE: Intraocular lens implantation in uveitis patients has been a controversial issue. The purpose of this study is to evaluate the visual and surgical outcomes of extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (PC IOL) implantation in a diverse group of uveitis patients. PATIENTS AND METHODS: The results of 39 cases of ECCE and PC IOL implantation in 30 patients with uveitis were retrospectively analyzed. Five patients (six eyes) had pars plana vitrectomies combined with ECCE and PC IOL implantation. Patient age ranged from 26 to 71 years (average, 53.0 years). Specific uveitic syndromes were determined for 22 patients (73.3%). The postoperative follow-up period ranged from 6 to 43 months (average, 20.3 months). RESULTS: Visual acuity improved postoperatively in 38 eyes (97.4%), and this improvement ranged from 1 to 11 Snellen lines (average, 7.5 Snellen lines). Visual acuity improved postoperatively to 20/40 or better in 32 eyes (82%). Seven eyes had visual acuity worse than 20/40, which was attributed to posterior segment abnormalities after ECCE and PC IOL implantation. Uveitis recurred in 20 eyes (51.3%), and postoperative cystoid macular edema (CME) was observed in 18 eyes (46.2%). In all cases, the recurrent uveitis and CME improved or resolved with corticosteroid therapy. CONCLUSION: These results suggest selected uveitis patients can have improved vision without unacceptable risk for 1 to 3 years after ECCE and PC IOL implantation.
