 Abstract
Purpose: We compared the posterior capsule rupture (PCR) rate between microscope versus intracameral illumination in phacoemulsification surgery performed by novice ophthalmologists.
Methods: We conducted a retrospective chart review of 300 eyes of 211 patients who underwent phacoemulsification by novice ophthalmologists from March 2012 to October 2017. Novice ophthalmologists (n = 6) were divided into those using microscope illumination (n = 4) and intracameral illumination users (n = 2). The first 50 cataract surgery cases of each novice ophthalmologist were reviewed. The results using a phacoemulsification machine and microscopy were the same. The intraoperative complications and learning curve in each case were evaluated.
Results: Phacoemulsifications performed by novice ophthalmologists showed a statistically significant difference in PCR rate between the microscope illumination (19.0%, 38/200) and intracameral illumination (4.0%, 4/100) groups (p = 0.001). The incidence of PCR was reduced to 22%, 18%, 16%, 12%, and 8% per 10 cases in the microscope group, while it was 15% in the first 10 cases and 0% in 50 cases thereafter in the intracameral illumination group.
Conclusions: Novice surgeons had a lower PCR rate during cataract surgery using intracameral illumination than using microscope illumination. Both groups showed a tendency for the PCR to decrease with increasing surgical cases, but the intracameral illumination group showed a shorter learning curve.
