Outcome of cataract extraction and posterior chamber intraocular lens implantation following glaucoma filtration surgery.

PURPOSE: To evaluate the outcome of cataract extraction (CE) after glaucoma filtering surgery (GFS). METHODS: A total of 77 eyes (77 patients) who underwent CE with posterior chamber intraocular lens (PCIOL) implantation following GFS by a single surgeon were reviewed. Main outcome measures were preoperative and postoperative intraocular pressures (IOPs), visual acuities, medications, astigmatism, bleb survival, time of surgical failure, complications, and success rate. RESULTS: Mean time interval between GFS and CE was 46.8+/-50.9 months (range, 2-348 months). The mean preoperative IOP was 13.9+/-4.7 mmHg (range 3-27 mmHg) and mean postoperative IOP at 3 weeks was 13.6+/-5.5 mmHg (range, 6-44 mmHg). The mean follow-up was 19.5+/-20.1 months (range, 1.4-73 months; median 10.6 months). Complete success was achieved in 59 eyes (76.7%). The cumulative probability of complete success was 91.3+/-3.7, 82.0+/-5.6 and 78.1+/-6.5% at the end of 6 months, 1, and 2 years, respectively. Visual acuity before CE was < or =20/50 in all eyes (100%). Visual acuity at last visit was > or =20/40 in 33 eyes (42.8 %), 20/50-20/80 in 30 eyes (39.0%), < or =20/100 in 14 eyes (18.2%). Risk factors identified for qualified success included age at CE>60 years, interval of < or =5 months between GFS and CE, use of preoperative glaucoma medications, and postoperative IOP >19 mmHg within 2 weeks. CONCLUSIONS: IOP and bleb function was maintained after CE with PCIOL implantation following successful GFS with good visual recovery.

Propionibacterium acnes endophthalmitis seven months after extracapsular cataract extraction and intraocular lens implantation.

We present a case of endophthalmitis caused by Propionibacterium acnes seven months following extracapsular cataract extraction and intraocular lens implantation. The markedly delayed clinical course of endophthalmitis associated with this organism appears to be highly stereotypical. Recognition and treatment of this complication of cataract surgery allows an excellent chance at cure.

Posterior synechiae in extracapsular cataract extraction with posterior-chamber intraocular lenses.

Posterior synechiae formation was studied in 294 consecutive cases of extracapsular cataract extraction with posterior-chamber intraocular lens implantation. The synechiae are mainly a cosmetic blemish and may hinder future pupillary dilation. Formation can be reduced by elimination of the iridectomy, elimination of routine mydriatic drops, and minimization of iris trauma at the time of surgery.

Subjective visual experience during extracapsular cataract extraction and intraocular lens implantation under retrobulbar anaesthesia.

PURPOSE: To investigate the subjective visual experience of patients during cataract surgery under retrobulbar anaesthesia. METHODS: One hundred cataract patients who underwent routine extracapsular cataract extraction and intraocular lens implantation under retrobulbar anaesthesia were interviewed by the authors on the same day after their operation regarding their visual experience in the operated eye during surgery. RESULTS: Forty-three men and 57 women were included in the study. Their mean age was 68.4 years (range 40-87 years). Their pre-operative best corrected visual acuity ranged from 6/12 to perception of light. Eighty-four eyes had no other ocular pathology apart from cataract. Twenty patients reported no light perception during the surgery. The rest reported that they could see light (80 patients), one or more colours (56 patients), movements (39 patients), flashes (36 patients), instruments (16 patients) and/or the surgeon's fingers or hands (10 patients). The colours seen included red (29 patients), yellow (29 patients), green (12 patients), blue (11 patients) and orange (2 patients). Fifteen patients saw a spectrum of colours similar to that of the rainbow. Forty-four patients reported that the brightness of light changed during the operation. Five patients found their visual experience frightening. There was no correlation between those who found the experience frightening and the sex or age of patient, presence of coexisting ocular pathology, duration of operation, whether the operation was the first or second cataract operation in the patient, or the type of visual sensation experienced. CONCLUSION: Many patients undergoing cataract surgery under retrobulbar anaesthesia experience a variety of visual sensations that may be frightening in a small proportion of cases.

Comparison of phacoemulsification and planned extracapsular cataract extraction in combined pars plana vitrectomy and posterior chamber intraocular lens implantation.

BACKGROUND AND OBJECTIVE: To compare two kinds of cataract removal methods combined with pars plana vitrectomy and posterior chamber intraocular lens (PC-IOL) implantation. PATIENTS AND METHODS: Cataract removal was performed by either phacoemulsification or extracapsular cataract extraction (ECCE) and followed by pars plana vitrectomy and PC-IOL implantation. Between May 1996 and June 2001, 31 and 22 patients with cataract and vitreoretinal disease were treated by phacoemulsification and ECCE, respectively, combined with pars plana vitrectomy and PC-IOL implantation. Preoperative demographic data and postoperative vision, astigmatism change, and complications were analyzed. RESULTS: The mean age of patients in the phacoemulsification and ECCE groups was 62.5 and 63.4 years, respectively. Diabetes mellitus was the most common underlying disease resulting in vitreous opacity. Vision improved in 87.1% of the phacoemulsification group and 59.1% of the ECCE group. The change in astigmatism after surgery was 0.92+/-1.08 D (P = .001) in the ECCE group and 0.25+/-0.74 D (P = .087) in the phacoemulsification group. There were fewer postoperative complications, including recurrent vitreous hemorrhage, increased intraocular pressure, and iris changes in the phacoemulsification group than in the ECCE group. CONCLUSION: Phacoemulsification and ECCE combined with pars plana vitrectomy and PC-IOL implantation are both effective surgical methods to achieve better and more rapid visual rehabilitation for patients with combined cataract and vitreoretinal disease. In this study, phacoemulsification combined with pars plana vitrectomy and PC-IOL implantation resulted in greater improvement in vision, less astigmatism change, and fewer postoperative complications.

Zonular dialysis during extracapsular cataract extraction in pseudoexfoliation syndrome.

Five patients with pseudoexfoliation syndrome (PES) and glaucoma developed extensive zonular dialyses during extracapsular cataract extractions. Weakness of the lens zonules or their attachments to the ciliary processes, which has been described in association with PES, may explain this complication. We believe that patients with PES are at particular risk for developing large zonular dialyses during extracapsular surgery. Preoperative phakodonesis, anterior chamber depth asymmetry, and excessive lens movement during the anterior capsulotomy should alert the surgeon to this problem.

Double-blind controlled trial to compare anti-inflammatory effects of tolmetin 2%, prednisolone 0.5%, and placebo in post-cataract extraction eyes.

This paper compares the efficacy of tolmetin, prednisolone, and placebo (vehicle only) in controlling post-cataract extraction inflammation in a double-blind trial involving 120 patients. Seventeen patients were excluded from analysis. The results of the 103 patients analysed showed that 94% of the prednisolone treated group was judged to have been successfully treated as compared with 53% of the tolmetin treated group and 46% of the vehicle treated group. The differences between the prednisolone treated group and the other two groups were statistically significant (p less than 0.001). No statistical significance was found between the tolmetin and vehicle groups.

Management of subluxated crystalline lenses with planned intracapsular cataract extraction and anterior chamber intraocular lens implantation.

PURPOSE: To review the visual and surgical outcome of planned intracapsular cataract extraction (ICCE) and anterior chamber intraocular lens (AC IOL) implantation for subluxated crystalline lenses. METHODS: Eight eyes of 7 patients with subluxated lenses which underwent planned ICCE, AC IOL implantation and peripheral iridectomy by one surgeon between September 1995 and November 1996 were prospectively followed-up to ascertain their visual and surgical outcome. RESULTS: There were 4 male and 3 female patients. Their mean age was 64.4 years (range, 39-86 years). Seven lenses were removed by cryoextraction while one was removed with the aid of a vectis. The mean post-operative follow-up was 11.6 months, (range, 3-22 months). Excluding 1 eye with pre-existing ocular pathology, all eyes achieved a best corrected visual acuity (BCVA) of 6/12 or better post-operatively. One of these eyes, in a schizophrenia patient, developed subluxation of the AC IOL and retinal detachment 11 months after the cataract surgery due to repeated eye rubbing. The final BCVA became 6/120 after successful repositioning of the AC IOL and retinal re-attachment surgery. One eye achieved a BCVA of 6/36 due to age-related macular degeneration. CONCLUSION: Our results show that planned ICCE and AC IOL implantation is a useful and safe procedure in the management of subluxated lenses.

Chronic Propionibacterium endophthalmitis after extracapsular cataract extraction and intraocular lens implantation.

We studied six cases of chronic, indolent intraocular inflammation that occurred after extracapsular cataract extraction and posterior chamber intraocular lens implantation. The inflammation was characterized by a delayed onset, and in three cases had the clinical appearance of a granulomatous iridocyclitis. Cultures of intraocular specimens obtained from six eyes yielded Propionibacterium; five yielded P. acnes. Pleomorphic gram-positive bacilli consistent with Propionibacterium were identified in cytologic or histopathologic studies in four of the six culture-positive cases. After surgical and medical therapy, the inflammation resolved. Postoperative Propionibacterium endophthalmitis may masquerade as a chronic iridocyclitis.

Peroperative microbial contamination of anterior chamber aspirates during extracapsular cataract extraction and phacoemulsification.

BACKGROUND: The normal conjunctival flora is one of the main sources of intraocular contamination during cataract surgery. The theory that the positive anterior chamber (AC) pressure during phacoemulsification (phaco), and the smaller wound utilised, might reduce the rate of contamination was studied. METHODS: The peroperative AC aspirates of 210 consecutive patients undergoing cataract surgery were assessed. In group 1, 100 patients underwent a standard extracapsular cataract extraction (ECCE). In group 2, 110 patients underwent phacoemulsification of the crystal-line lens through a scleral tunnel. AC aspirates from the Simcoe irrigation/aspiration cannula (group 1) and phaco probe (group 2) were collected and microbiological studies performed after direct and enrichment cultures. RESULTS: There were 29 (29%) positives in the ECCE group compared with 22 (20%) positive cultures from AC aspirates in the phaco group. Coagulase negative staphylococcus (CNS) was the commonest contaminant in both groups. CONCLUSION: Although there was a higher rate of AC contamination during ECCE, the difference was not statistically significant (p > 0.10, chi 2 = 2.31).
