METHODS: A retrospective collection of 105 cases(105 eyes)of cataract patients with corneal opacities who underwent cataract phacoemulsification combined with intraocular lens implantation at the Army Eye Center of Xinjiang Military Region General Hospital from January 2014 to March 2019. All patients received cataract phacoemulsification removal and intraocular lens implantation. Apply the trypan blue capsule staining agent during the operation and observe the anterior capsule staining, the success rate of continuous annular capsulorhexis, the rupture of the posterior lens capsule and the implantation of the intraocular lens capsule. Patients were followed up at 1d, 1wk, 1 and 3mo after surgery. Observe the success rate of capsulorhexis during operation, the best corrected visual acuity(BCVA, LogMAR)before and after surgery, and postoperative complications.

RESULTS: All patients underwent phacoemulsification with intraocular lens implantation. During the operation, all continuous ring-shaped capsulorhexis were successfully completed through the application of trypan blue capsule staining(trypan blue)dye, and other measures including application of iris hook and irisotomy were taken. A foldable intraocular lens was implanted in 105 eyes. After 3mo of follow-up observation, the BCVA of the operation eye was 0.82±0.10 compared with the preoperative BCVA 3.12±0.14,and there were statistical differences(t=174.893, P<0.01).

CONCLUSION: Cataract phacoemulsification can safely and effectively improve the vision of patients with cataract and corneal opacity. The application of assistive technologies such as capsule staining, iris hooking, and iris resection can effectively reduce the risk of cataract surgery in patients with cataract and corneal opacity, improve the safety of surgery, and increase the success rate of surgery.
