Incidence of retinal detachment after cataract surgery and neodymium: YAG laser capsulotomy.
The objective of this retrospective study was to determine the incidence of retinal detachment (RD) in patients following cataract extraction with intraocular lens placement and after neodymium:YAG (Nd:YAG) laser capsulotomy. This study comprised 1092 patients (1168 eyes) who had cataract extraction and related procedures between January 1986 and December 1992 identified from the coding and billing database. Of the 1092 patients, 215 (244 eyes) had had Nd:YAG laser capsulotomy. Their charts were reviewed for incidence of RD, and these data were correlated with age, sex, axial length, surgical complications, and other surgical procedures done at the time of cataract extraction. The incidence of RD following phacoemulsification alone was 0.75% (6/799), with a mean time between cataract extraction and RD of 11.6 months. The cases of RD after extracapsular cataract extraction, combined phacoemulsification and trabeculectomy, combined extracapsular cataract extraction and penetrating keratoplasty, and combined phacoemulsification and anterior vitrectomy were too few to draw any conclusions. The incidence of RD following Nd:YAG laser capsulotomy was 0.82% (2/244), with a mean time of 32 months between cataract surgery and capsulotomy and 13.5 months between capsulotomy and RD. There was a statistically significant higher incidence of RD after posterior capsule rupture and anterior vitrectomy than after uncomplicated phacoemulsification (2/12 versus 6/799). In conclusion, the rate of RD after uncomplicated phacoemulsification was less than or similar to the rate found in other recent studies. It was not statistically different from the rate following phacoemulsification and Nd:YAG laser capsulotomy (0.82%). This study confirms the increased risk of RD following posterior capsule rupture and anterior vitrectomy.
