Rigid pupil and weak zonules are the most significant factors which complicate phacoemulsification in the eyes with pseudoexfoliation syndrome (PES).
PURPOSE: To prove advantage of using of the capsular tension rings in the eyes with pseudoexfoliation syndrome.
MATERIAL AND METHODS: We analyzed the results of 532 phacoemulsifications in 519 patients with cataract. The age range of the patients was 34 to 82 years. Operations were performed by 1 surgeon with Universal II (Alcon) and CV – 24000AP (Nidek). Phaco technique «Stop&Chop» was employed. We formed three groups: 83 eyes with PES were executed phacoemulsification without using capsular tension rings, 48 eyes with PES were operated with using capsular tension rings, and the control group included 401 eyes without pseudoexfoliation and glaucoma.
RESULTS: There were 8 cases (9.6%) of capsular disruptions in the 1st group. It is necessary to note, that the preoperatively subluxation of the lens took place in 6 cases of broken capsules. There were 2 eyes (4.1%) with the capsular bag defects in the 2nd group. There were 5 cases (1.2%) of capsular disruption in the control group. There were not any cases of IOL decentration in all patients with PES in terms 3 years after operation.
CONCLUSIONS: The capsular tension ring helps to avoid capsular and vitreous complications during phacoemulsification in the eyes with PES. Subluxation of the lens is the absolute indication to the implantation of the capsular tension ring.
