1. The indications for removing an intraocular lens (IOL) are: A. Chronic uveitis B. Endothelial corneal dystrophy C. Uncontrollalbe glaucoma D. Metal loop cutting pupillary sphincter E. Gross decentration of IOL (fibrous bands) F. Extraocular dislocation of IOL G. Recurrent severe hyphema H. Development of rubeosis iridis I. Removal of iris (1) Iris tumor (2) Epithelial downgrowth J. Endophthalmitis K. Unilateral IOL in pending bilateral aphakia 2. The following may be indications for removing and/or replacing and/or replacing an IOL: A. Wrong dioptric power B. Foreign body attached to IOL C. IOL covered with pigment D. Repair retinal detachment after extracapsular cataract extraction E. Choyce lens too short F. Dannheim IOL with absorbed supramid loop tips G. Dislocated Ridley IOL H. Sclero-conjunctival erosion of Strampelli's "external-fixation" IOL loop. The preceding analysis of problem areas is meant to specifically define when and why to remove or replace an IOL, or institute alternative forms of treatment. One is advised to obtain consultation or a second opinion before embarking on lens-removal surgery.

The postoperative results of 210 consecutive eyes in 177 patients who had simultaneous penetrating keratoplasty, extracapsular cataract extraction, and posterior chamber intraocular lens (IOL) implantation (triple procedure) were reviewed. All procedures were performed by one surgeon between January 1980 and December 1989. The most common diagnosis requiring a triple procedure was Fuchs' endothelial dystrophy. The remainder of the patients required the procedure for either corneal scarring, keratoconus, or Chandler's syndrome. Of the 210 grafts, 191 (91%) remained clear with a mean follow-up of 53 months (range 6 to 116 months). The mean preoperative keratometry (K) reading (n = 161) was 44.51/44.85 (SD 4.86/4.94), and the mean postoperative K reading (n = 111) was 44.29/43.50 (SD 3.83/3.63). The mean IOL power (n = 196) was + 20.87 diopters (D) (SD 2.86). The mean postoperative best visual acuity (n = 166) was 20/65 with a range from 20/20 to less than 20/400, although 61% had 20/50 acuity or better and 92% had 20/100 acuity or better. The mean spherical correction in 155 eyes was - 1.38 (SD 2.89), and the mean positive refractive cylinder was + 3.21 (SD 2.20). One hundred forty six of the 155 eyes with reported refractions (96%) had 6 D or less of refractive cylinder. Correlation of the recipient-donor disparity % and refractive cylinder was significant such that as disparity increased refractive cylinder increased (r = 0.197, P = .021). Correlation of the recipient-donor disparity % and keratometric cylinder indicated a similar trend but was not significant (r = 0.105, P = .310).

We describe a patient with Chandler's syndrome variant of the iridocorneal endothelial syndrome in whom ectopic Descemet's membrane was found intraoperatively on the anterior surface of the lens. Initially, the membrane was confused with the anterior lens capsule during extracapsular cataract extraction, leading to the performance of a pseudocapsulorrhexis. Electron microscopy disclosed that the epilenticular membrane was composed of multiple layers of abnormal basement membrane consistent with the iridocorneal endothelial syndrome.
