PURPOSE: To describe an improved technique for secondary IOL implantation in constricted capsular bag in aphakic eyes.
SETTING: This study was designed and carried out in the department of Ophthalmology, Shanghai General Hospital (Shanghai First People's Hospital).
DESIGN: This is a retrospective study which evaluate the post-operative effect of the two-steps secondary IOL implantation.
METHOD: 21 eyes of 21 patients who underwent primary cataract surgery from June 2020 to September 2020 were enrolled. Two-steps IOL implantation was performed. Patients were followed up with ophthalmic examinations.
RESULTS: Of all 21 eyes, the capsular bags were reopened and the IOL were implanted into the bag. During follow-up, the mean age was 62.3 ± 7.3 (range, 44-81) years and mean interval between the primary surgery and secondary IOL implantation was 23.5 ± 9.6 (range, 4.1-78.3) weeks. A marked improvement of postoperative mean BCVA was noticed (pre 20/84 Snellen, 0.62 ± 0.26 logMAR equivalent, and post 20/44 Snellen, 0.34 ± 0.33 logMAR equivalent; p = 0.001). The mean SE also improved from + 10.32 ± 5.05D at baseline to -2.68 ± 1.36D at the last follow-up time (p < 0.001). The mean IOP showed no significant difference (pre 17.62 ± 4.66 mmHg, post16.84 ± 4.73 mmHg; p = 0.6860) and the corneal endothelial cell density decreased about 11.04 ± 10.84% (from 2483 ± 218.43 cells/mm2 to 2190 ± 361.36 cells/mm2 p = 0.0029).
CONCLUSION: The two-steps capsular bag reopening method can be achieved in majority of cases with stable IOL position and better visual outcome.
