Clinical observation on retroillumination assisted continuous circular capsulorhexis

Abstract

Objective To observe the application of illuminator guided retroillumination assisted continuous circular capsulorhexis. Methods A prospective study. Thirty eyes of 30 cases with cataract with vitreous hemorrhage, with poor fundus red reflex, from Sep. 2016 to Aug. 2017 in this hospital, were enrolled. After the ophthalmic endoilluminator was inserted into the vitreous, the endoilluminator was irradiated forward from the posterior lens capsule, then continuous circular capsulorhexis was performed. Phacoemulsification and vitrectomy were carried out routinely. The followed-up time was 8-12 months. Results The continuous circular capsulorhexis and phacoemulsification were performed successfully in all 30 eyes without any posterior capsule rupture. Vitreous hemaorrhage was completely removed, and retinal diseases was properly treated. The visual acuity before operation was HM-0.04 in 27 eyes(90.00%) and 0.05 in 3 eyes(10.00%). Postoperative visual acuity of all patients were 0.05 or better. The difference of visual acuity was statistically significant between before and after operation (χ2=49.091, P=0.000). Conclusion The illuminator guided retroillumination assisted continuous circular capsulorhexis can effectively solve the difficulty of poor red light reflex for cataract patients with vitreous hemorrhage.
