Iris modifications following extracapsular cataract extraction with posterior chamber lens implantation.

We prospectively examined 94 eyes of 93 consecutive patients who had planned extracapsular cataract extraction or phacoemulsification with posterior chamber intraocular lens (IOL) implantation. The observed postoperative iris biomicroscopic modifications are described and classified. Iris synechial formation was more frequently observed in eyes with pseudoexfoliation syndrome, when an irregular anterior capsulotomy was performed, when the IOL was other than in the bag, and in cases of postoperative fibrinous exudation. Synechias occurred more frequently in intraoperatively injured iris areas. Pupil capture was the only postoperative iris modification that was observed to affect visual acuity. The maximal postoperative dilation was greater and the pupillary photic reaction was significantly less modified postoperatively (P = .0058) when the IOL was fixated within the capsular bag.

Corneal thickness after cataract extraction with air in the anterior chamber.

A total of 135 patients had the corneal thickness measured prior to cataract extraction. The chamber was re-established by air in 86, while the remainder acted as controls. On the second postoperative day the corneal thickness had increased by 12.7% in the air-inflated group, and by 17.6% in the control group. On the sixth postoperative day the increases in thickness were 7.2 and 11.1% respectively. On follow-up control 6 to 12 months later the corneal thickness was as before the operation. Epithelial oedema was significantly more frequent in the control group. The conclusion is drawn that an air bubble in the anterior chamber has no unfavourable effect on the corneal endothelium. On the contrary, it seems to protect the endothelium from postoperative damage.

Pars plana vitrectomy for retinal detachment due to internal posterior ophthalmomyiasis after cataract extraction.

BACKGROUND: The authors report a case of posterior internal ophthalmomyiasis causing vitreous haemorrhage and retinal detachment after uncomplicated cataract extraction. CASE REPORT: The patient suffered an abrupt vitreous haemorrhage 9 days after ECCE and posterior chamber IOL implantation. After 2 months the haemorrhage did not clear up and a retinal detachment arose. The patient underwent encircling scleral buckle, pars plana vitrectomy and fluid-gas exchange. In course of intervention the surgeon removed from the vitreous chamber a 14-mm-long round worm subsequently identified as a dipterous larva of the Sarcophagidae family. DISCUSSION: The patient showed no sign of subretinal tracking or retinal breaks or holes. The sclerocorneal surgical wound seems the most likely site of entrance of the parasite, and this would then be the first reported case of myiasis with no RPE tracking.

The effect of topical steroid on postoperative corneal edema and endothelial cell loss after intracapsular cataract extraction.

In a prospective study of 89 patients the postoperative corneal edema and endothelial cell count was studied after cataract extraction. A double blind investigation was performed as the patients during the first 6 postoperative days were treated with three different types of eye-drops: Maxidex, Pred-Forte 1% or placebo, all containing Benzalkonium Chloride 0.004%. The content of steroid in Maxidex and Pred-Forte was equivalent. We found no significant difference in estimates of endothelial cells in the three groups postoperatively. Corneal edema was less in the two groups treated with steroid. There was no significant difference between the two postoperative groups (p > 0.05) treated with Maxidex and Pred-Forte. The group treated with Pred-Forte showed significantly less postoperative corneal edema, calculated as the graphical area represented by the increase of central corneal thickness (CCT) after operation.

Propionibacterium-associated endophthalmitis after extracapsular cataract extraction. Review of reported cases.

Sixteen cases of previously reported culture-proven Propionibacterium-associated endophthalmitis after extracapsular cataract extraction (ECCE) are reviewed. The inflammation was observed 2 to 10 months after surgery and occurred after laser posterior capsulotomy in four cases. Clinically, it appeared as a chronic iridocyclitis characterized by granulomatous-appearing keratic precipitates (5 cases), hypopyon (10 cases), and a white plaque on the posterior capsule or intraocular lens (IOL) implant (8 cases). Response to corticosteroid treatment was transient. Surgical intervention was required between 1 and 16 months after the inflammation began and included removal of the IOL and capsular bag via the limbus in 7 cases and pars plana vitrectomy in 11. Intravitreal antibiotics were administered in 12 cases. Postoperative visual acuity ranged from 20/20 to count fingers, with 11 of 16 patients recovering visual acuity of 20/40 or better. Propionibacterium-associated endophthalmitis should be suspected if chronic indolent intraocular inflammation develops after ECCE. Intraocular specimens should be obtained and submitted for aerobic and anaerobic culture and cytologic/histopathologic studies. Based on the clinical courses of these patients, recommendations for management are discussed.

Extracapsular cataract extraction and posterior chamber intraocular lens implantation in glaucomatous eyes.

Two hundred ninety-six eyes of 250 patients undergoing extracapsular cataract extraction (ECCE) with or without the implantation of a posterior chamber intraocular lens (PC-IOL) were studied. Pre-existing glaucoma of varying severity was present in 139 eyes and no known ocular pathology other than cataract in 157 eyes. During the first eight weeks following surgery, intraocular pressure elevations greater than or equal to 15 mmHg above baseline were seen in 23% of glaucomatous eyes controlled before surgery with glaucoma medications, in 39% of glaucomatous eyes controlled before surgery with argon laser trabeculoplasty, and in only 3% of nonglaucomatous eyes. The implantation of a PC-IOL did not influence the incidence of postoperative intraocular pressure (IOP) elevations. Among glaucomatous eyes with severe preoperative visual field loss (split fixation or central island less than or equal to 10 degrees), 9.7% had worsening of visual field after surgery. Open angle glaucoma of unclear etiology developed in 1.4% of normal eyes following uncomplicated ECCE with PC-IOL implantation. Surgical techniques the authors have found useful in glaucomatous eyes undergoing ECCE with PC-IOL implantation are discussed.

[Extracapsular cataract extraction with posterior chamber IOL implantation].

From 1983 to 1989, 242 cataract patients (260 eyes) were performed extracapsular cataract extraction with posterior chamber IOL implantation. 157 patients (171 eyes) were followed up 3-69 months, averaging 18.3 months. Visual acuities of 1.0-1.5 were achieved in 79.4% and 0.5 or better in 95.2% of the eyes when cases of non-operative poor vision were excluded. Complications were few and the results had been stable.

Microscope light-induced maculopathy in combined penetrating keratoplasty, extracapsular cataract extraction, and intraocular lens implantation.

A characteristic retinal phototoxicity reaction was noted in four patients who underwent penetrating keratoplasty, extracapsular cataract extraction (ECCE), and intraocular lens (IOL) implantation. This complication has been well documented in association with other ocular procedures, but only one previous similar case has been reported. The authors bring this potential complication to the attention of corneal surgeons, discuss the risk factors, and offer suggestions on prevention.

The "trap door" anterior capsulectomy technique for extracapsular cataract extraction with posterior chamber intraocular lens implantation in the capsular bag.

A technique for performing the anterior capsulectomy in extracapsular cataract extraction is described. The "trap door" anterior capsulectomy facilitates removal of 12 o'clock cortex by retracting the superior iris. Also, the anterior capsular flap acts as a lens glide during insertion of the IOL, and as a guide for the haptic during placement of the superior loop in the superior fornix of the capsular bag.

Retinal burns occurring at cataract extraction.

Paramacular changes presumably induced by operating microscope light have been described previously in six patients who had undergone extracapsular cataract extraction with posterior chamber lens implantation. Twelve additional patients are reported, including pseudophakes and nonpseudophakes, macular and paramacular burns, and no visual loss and severe visual loss. Burns occurred in spite of filters and light barriers used in some cases. Light sources were tungsten bulb or halogen/fiberoptic. Three cases had essentially normal preoperative angiography. Currently recommended safety measures have not eliminated this complication.

Extracapsular cataract extraction and posterior chamber lens implantation in eyes with preexisting glaucoma.

Fifty eyes of 40 patients with glaucoma underwent extracapsular cataract extraction with posterior chamber lens implantation. Their visual results and early postoperative complications were compared with those of eyes in an age-matched group of patients without glaucoma after the same procedure. Substantial increases in early postoperative intraocular pressure (IOP) occurred in 62% of the glaucomatous eyes and in only 10% of the normal eyes. The level of best visual acuity was slightly worse (20/40) on average in the glaucomatous eyes than in the nonglaucomatous eyes (20/25). At six months after surgery, 82.5% of the nonfiltered glaucomatous eyes needed the same number of or additional glaucoma medications to maintain an IOP of less than 20 mm Hg. Ten of the glaucomatous eyes underwent trabeculectomy along with cataract surgery due to inadequate IOP control while the patient was receiving maximum medical therapy. Control was substantially improved, with 100% of these patients receiving the same number of or fewer medications at six months. By one year, only 30% of these patients required the same number of medications postoperatively as preoperatively, but all had IOP control.

Practically corrected visual acuity after extracapsular cataract extraction with or without intraocular lens implantation.

We examined retrospectively a total of 171 patients (236 eyes) who had undergone extracapsular cataract extraction (ECCE) with or without intraocular lens implantation (IOL). The best and practically corrected visual acuities were determined 6 months after surgery. Practically corrected visual acuity of the ECCE group was significantly worse than that of ECCE plus IOL group of patients who had undergone unilateral cataract surgery. In patients who had undergone bilateral surgery, visual improvement was almost optimal in both groups. With regard to practically corrected visual acuity, ECCE plus IOL was the preferable procedure for elderly patients who had had unilateral cataract.
