Intraoperative complications of phacoemulsification in eyes with and without pseudoexfoliation.
ABSTRACT To determine the intraoperative complications in a large series of phacoemulsification procedures, including patients with and without pseudoexfoliation, excluding those with marked phacodonesis or lens subluxation.
Department of Ophthalmology, Carmel Medical Centre, Haifa, Israel.
This institutional case-control study included 1501 consecutive phacoemulsification procedures: 137 eyes with pseudoexfoliation and 1364 eyes without this condition. Baseline demographics and clinical factors were collected from the medical files. A comparative analysis of the incidence of intraoperative complications in eyes with or without pseudoexfoliation was calculated. Univariate analysis and multiple logistic regression were used to identify ocular factors that predicted intraoperative complications.
There was no significant difference (P>.05) in the rate of intraoperative complications between the pseudoexfoliation (5.8%) and control (4.0%) groups. There were no significant differences in the incidence of capsular breaks, vitreous loss, and zonular ruptures without vitreous loss in the 2 groups. Pseudoexfoliation did not confer a statistically higher risk for intraoperative complications (odds ratio 1.62, 95% confidence interval 0.74-3.55).
Phacoemulsification by experienced surgeons is safe in eyes with pseudoexfoliation without marked phacodonesis or lens subluxation.

ABSTRACT: Posterior capsular rupture (PCR) is an infrequent complication of cataract surgery that can lead to significant ocular morbidity and permanent vision loss. In the setting of PCR, the primary objective is the safe and thorough evacuation of vitreous and lens fragments from the anterior segment. The secondary objective is the stable placement of an intraocular lens (IOL) selected for best refractive outcomes. Expedited referral to vitreoretinal specialists is recommended for management of posteriorly dislocated lens material and surveillance for retinal injury. It is the intention of this review to present current guidelines for the management of PCR. There are new techniques available to anterior and posterior segment surgeons in the setting of PCR. Endoillumination may facilitate visualization during anterior vitrectomy and the IOL may be used as a pupillary barrier to prevent loss of lens fragments. When secondary procedures are needed, early return to the operating room and small-gauge pars plana techniques may reduce patient morbidity. When approached carefully and systematically, patients may have good outcomes in the setting of PCR. Recent advancements in instrumentation and technique encourage further study and may lead to new standards of care.Current opinion in ophthalmology 01/2014; 25(1):26-34. · 2.49 Impact Factor

ABSTRACT: To analyze the rate of intraoperative complications, reoperations, and endophthalmitis with phacoemulsification, manual small-incision cataract surgery (SICS), and large-incision extracapsular cataract extraction (ECCE). Aravind Eye Hospital, Madurai, India. Retrospective cohort study. This study comprised consecutive cataract surgeries performed during a 12-month period. All surgical complications and endophthalmitis cases were tabulated and analyzed for each of 4 surgeon groups (staff, fellows, residents, visiting trainees). Within each surgeon group, complication rates with phacoemulsification, manual SICS, and ECCE were compared. The surgical distribution was 20,438 (26%) phacoemulsification, 53,603 (67%) manual SICS, and 5736 (7%) ECCE. The overall intraoperative complication rate was 0.79% for staff, 1.19% for fellows, 2.06% for residents, and 5% for visiting trainees. Extracapsular cataract extraction had the highest overall rate of surgical complications (2.6%). The overall complication rate was 1.01% for manual SICS and 1.11% for phacoemulsification. However, the combined complication rate for trainees was significantly higher with phacoemulsification (4.8%) than with manual SICS (1.46%) (P<.001). The corrected distance visual acuity was better than 6/12 in 96% after phacoemulsification complications and 89% after manual SICS complications (P<.001). There were 27 cases (0.04%) of endophthalmitis but no statistical differences between surgical methods or surgeon groups. For staff surgeons experienced with both phacoemulsification and manual SICS, intraoperative complication rates were comparably low. However, for trainee surgeons, the complication rate was significantly higher with phacoemulsification, suggesting that manual SICS may be a safer initial procedure to learn for inexperienced cataract surgeons in the developing world.
