We treated 650 consecutive cases of phacoemulsification with total capsulectomy. More than 91% of cases had best corrected visual acuities of 20/40 or better. In those with vision of 20/100 or less (3.5%) no cause for decreased acuity could be related to the surgery; 94% of cases had less than 1.5 diopters of residual astigmatism. Vitreous loss, occurring in 2.9% of cases, could be related to initial inexperience and errors in technique rather than patient age. Postoperative complications included transient striate keratitis (2.3%), persistent corneal edema (one case), cystoid macular edema (2.8%), and aphakic retinal detachments (2.6%). There were no hyphemas, flat or shallow anterior chambers, or filtering blebs postoperatively. We believe that this technique of total cataract extraction through a 3-mm incision yields the same results as an intracapsular extraction, but with less complications, and all the benefits of a small limbal incision.

Vitreous loss occurred in 50 of 475 consecutive eyes undergoing infantile cataract aspirations over a 10-year period. Vitreous loss occurred in eyes predisposed to such loss and in other eyes following the use of faulty instrumentation, poor surgical judgment, or from errors in operative technique. Vitreous loss was managed by the techniques outlined by Castroviejo and Maumanee. An analysis of this series revealed that the operative loss of vitreous in children does not predispose to undesirable sequelae. Postoperative complications are not correlated with the loss of vitreous itself, but rather with the presence of other coincident ocular pathology and/or the persistence of vitreous in or attached to anterior chamber structures. The final attained visual acuity in patients suffering vitreous loss is not different from the average of the same population. Although vitreous loss consequences may be minimized, the authors do not advocate the disturbance of the intact vitreous face either accidentally or intentionally.

We performed a retrospective study on 45 patients admitted to the Rotterdam Eye Hospital and the Ophthalmic Department of the Academic Medical Center in Amsterdam with pseudophakic endophthalmitis. Vitreous loss during cataract extraction was associated with a significantly increased risk of postoperative endophthalmitis when compared with uncomplicated cataract extraction (p < 0.0001). The incidence of pseudophakic endophthalmitis in diabetic patients was not significantly higher as compared to non-diabetic patients. Vitrectomy in the treatment of postoperative endophthalmitis did not improve the final visual acuity, probably because of selection bias. Methicillin and cephazolin, used intravitreally against gram-positive organisms, failed to provide a good coverage for endophthalmitis due to Staphylococcus epidermidis.

The authors retrospectively analyzed the visual outcome and incidence of complications of 181 consecutive cases of phacoemulsification performed by eight third-year ophthalmology residents. A posterior chamber intraocular lens was implanted in 179 of these eyes. Vitreous loss occurred in 5.5% of cases. The overall incidence of posterior capsule rupture was 9.9%; of the 18 posterior capsular ruptures, 72% were detected during cortical removal and 22% during nuclear emulsification. Postoperative follow-up for 177 eyes was at least 2 months, and 70% were followed for 6 months or longer. Final best corrected visual acuity of 20/40 or better was obtained in 92.6% of eyes. These results are comparable with previous reports of residents' experience in performing planned extracapsular cataract extraction. With appropriate training and faculty supervision, residents learning to perform phacoemulsification and intraocular lens implantation can achieve acceptable results.

Vitreous loss is a dreaded complication of cataract surgery, especially so with IOL implant which then may have to be abandoned. Thirty three cases of IOL implants, either anterior chamber or posterior chamber, after vitreous loss done in the past 3 years were studied. Of these, 18 (55%) had a final visual acuity of 6/18 or better and none was worse than 6/60. The postoperative complications and findings and a review of literature are discussed.

To clarify the risk factors of proliferative vitreoretinopathy (PVR) in aphakia, the clinical features of 25 aphakic eyes with PVR were statistically analyzed and compared with a control group of 157 aphakic eyes with non-PVR rhegmatogenous retinal detachment. The statistically significant (P less than 0.05) factors that predisposed patients to PVR in aphakia were as follows: a history of vitreous loss on cataract surgery, retinal detachment developing within 3 months after cataract extraction, duration of retinal detachment longer than 3 months, break larger than three disc diameters, and choroidal detachment. Vitreous loss is believed to play the most important role in the development of PVR in aphakia.

Thirty-nine eyes with clinical cystoid macular edema (CME) following extracapsular cataract extraction and intraocular lens (IOL) implantation were reviewed retrospectively. Chronic CME, defined as clinically symptomatic CME persisting more than 6 months, developed in 14 of the 39 eyes (36%): in 5 of the 7 (71%) eyes in which vitreous loss occurred and anterior chamber IOLs were implanted; and in 9 of 32 (28%) eyes in which no complications occurred and posterior chamber IOLs were implanted. The mean duration between diagnosis and last follow-up visit was 34 months. Only 4 of the 14 eyes (29%) with chronic CME achieved a visual acuity better than 20/40. Vitreous loss did not affect long-term visual prognosis.

Phacoemulsification was performed in 125 eyes (123 patients) selected from 145 eyes (143 patients) referred for planned extracapsular cataract extractions and intended posterior chamber intraocular lens implantations. These procedures were the first clinical phacoemulsification operations performed by the author. In the total material, lesion of the posterior capsule or zonules occurred in 7 eyes (4.9%). Vitreous loss occurred in 3 of these eyes (2.1%). In cases with vitreous loss the operative strategy was changed to implantations of anterior chamber lenses. Five of the 7 eyes that experienced intraoperative complications, had preoperative complicating conditions other than cataract. Visual acuity 6 to 12 weeks postoperatively was 6/12 or better in 87% (126/145) of the eyes. Excluding preoperative posterior segment pathology, 98.4% (126/128) achieved this visual acuity. This study demonstrates that it is possible to include phacoemulsification as the main treatment modality in planned ECCE operations without significant increase in complication rates even for a 'beginning phacoemulsification surgeon'.

Vitreous loss is a serious complication of cataract surgery. Following vitreous loss it is common practice to perform a primary implantation of an anterior chamber lens (AC-IOL). We retrospectively analysed 642 consecutive cases of cataract extraction performed between 1983 and 1986 with special attention to those patients in whom vitreous loss occurred and an AC-IOL was placed. There were 27 such cases, and 24 of these were available for follow-up. Eighteen (75%) had visual acuity of 20/40 or better. All six patients (25%) who had a visual acuity of less than 20/40 in the operated eye had a functional visual acuity of 20/200 or less. Complications that occurred in this group are discussed. We are concerned that the complications associated with vitreous loss and with AC-IOLs may be acting in concert to cause visually disabling results.

Vitreous loss is a serious complication of cataract surgery. It has been suggested that high rates of vitreous loss may be an inevitable consequence when residents are learning extracapsular cataract extraction (ECCE). The authors retrospectively analyzed all (n = 936) cataract operations done by second- and third-year residents in a single Veterans Administration hospital from 1982 through 1988. Between 1982 and 1985, the incidence of vitreous loss was 10.3%. In 1985, a new program of resident surgical education was introduced, and the incidence from 1985 through 1988 declined to 3.2% (P less than 0.001). Statistical analysis confirms that this decrease cannot be attributed to any individual surgeon, class of residents, or year of surgery. The authors believe that an educational program including practice surgery, graded responsibility, and experienced assistance may be responsible in part for dramatically reducing the rate of this serious complication during surgery done by the beginning resident.
