Retinal detachment after extracapsular cataract extraction with posterior chamber intraocular lens.

ABSTRACT

The authors reviewed 3065 consecutive cases of extracapsular cataract extraction with posterior chamber lens implant (ECCE-PC IOL) and found the incidence of retinal detachment to be 1.4% overall (44/3065) and 1.7% in a group of eyes followed for at least 1 year (40/2330). Retrospective analysis of the retinal detachment (RD) group (n = 44) showed the patients to be significantly younger than the overall group (n = 3065) (P less than 0.0001). Comparison with an age-matched group of 302 eyes without RD showed higher rates of RD in males (P = 0.0013) and in eyes with axial eye length (AEL) greater than 25 mm (P less than 0.0001). No significant correlation was found between RD and PC IOL manufacturer, phacoemulsification (PKE), or primary discission. Sixty-four percent of RDs occurred within 1 year of cataract operation. Only 10% occurred more than 2 years later. Visual results in eyes with ultimate anatomic success of RD repair (43 of 44 eyes, averaging 15 months follow-up) are substantially better than previously reported in series with other types of IOLs (96% greater than or equal to 20/40 if the macula was not involved, 75% greater than or equal to 20/40 if the macula was involved).
