Phacoemulsification and silicone oil removal through a single corneal incision1
Section snippets
Patients and methods
Thirty-four eyes of 34 consecutive patients undergoing cataract extraction with removal of silicone oil between March 1995 and March 1996 were entered prospectively into this study (Table 1). All patients were under the care of a consultant from the Vitreo retinal Service of Moorfields Eye Hospital and previously had undergone complicated retinal detachment repair with infusion of 1000 centistoke (cs) silicone oil between 3 and 24 months before the development of cataract.
Information obtained
Results
The study consisted of 34 eyes of 34 consecutive patients (Table 1). The age at the time of cataract surgery ranged from 20 to 94 years (mean age, 58 years). There were 13 females and 21 males. The interval between placement of silicone oil and subsequent cataract surgery ranged from 2 to 19 months (mean, 7.5 months). All but three patients were British and white. The three who were not white consisted of one black male originally from Africa, one male from Iran, and one female from Gibralter.
Discussion
The use of silicone oil with vitrectomy in the repair of complex retinal detachments is becoming more common. The use of this method in phakic eyes invariably leads to the formation of cataracts, even with early silicone oil removal.1, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17 The exact mechanism for the formation of cataracts remains somewhat controversial and probably is contributed to by both the placement of the silicone oil against the posterior lens capsule4 as well as instigation of
