Abstract:
Objective:To investigate the clinical efficacy and safety of phacoemulsification and intraocular lens (IOL) implantation combined with a modified iris cerclage for cataract with mydriasis.Methods:A clinical retrospective study was conducted. Six eyes of 6 patients with cataract and mydriasis were treated with phacoemulsification and IOL implantation combined with modified iris cerclage in Department of Ophthalmology, the Affiliated Changzhou No.2 People’s Hospital of Nanjing Medical University, from January 2018 to September 2022. The best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal endothelial cell count (CECC), pupil diameter and photophobia scores were statistically analysed by paired sample t test at 3 days before surgery and 3 months after surgery. The pupil shape, IOL position, intraoperative and postoperative complications were observed. P<0.05 was considered statistically significant. Results:Postoperative follow-up with all patients lasted 3 to 6 months. The BCVA at the final follow-up (0.73±0.16) was significantly improved in all 6 patients compared with that of before surgery (0.43±0.12), with statistically significant difference ( P<0.05). There was no significant difference in IOP and CECC before and after surgery ( P>0.05). The pupil diameter after surgery was significantly smaller than that before surgery ( P<0.05). The postoperative photophobia score was significantly lower than that before surgery ( P<0.05). Pupils in all 6 eyes were round-like, in a central position and without an iris capture of IOL. There was no serious intraoperative or postoperative complication. Conclusion:Phacoemulsification and IOL implantation combined with modified iris cerclage is a safe and efficient procedure that can effectively improve the visual acuity, reduce the pupil diameter, improve photophobia symptom and enhance the visual quality in patients with cataract combined with mydriasis.
