VITREORETINAL OUTCOMES FOLLOWING SECONDARY INTRAOCULAR LENS IMPLANTATION WITH PARS PLANA VITRECTOMY

Area of Science:

• Ophthalmology
• Retina Surgery

Background:

• A retrospective cohort study analyzed 561 adult patients who underwent secondary intraocular lens (IOL) implantation.
• The study period was from April 2015 to December 2020, involving vitreoretinal surgeons at a single institution.

Purpose of the Study:

• To compare the outcomes of different secondary intraocular lens (IOL) implantation techniques.
• To assess primary outcomes including postoperative retinal tears and rhegmatogenous retinal detachment.
• To evaluate secondary outcomes such as intraoperative endolaser use, intraoperative retinal tears, and the need for further IOL surgery.

Main Methods:

• Retrospective cohort study design.
• Inclusion of 561 adult patients undergoing secondary IOL implantation.
• Assessment of patient history, intraoperative/postoperative complications, and outcomes stratified by IOL type: anterior chamber IOL, scleral sutured IOL, scleral fixated IOL, and sulcus IOL.

Main Results:

• The incidence of intraoperative retinal tears was 7.3%, with no significant difference between techniques.
• Intraoperative endolaser use was observed in 17.5% of cases, also not significantly different across techniques.
• Postoperative rhegmatogenous retinal detachment rates were similar across all techniques (4.6% overall), with no statistically significant variations.
• Repeat IOL surgery rates trended higher for sulcus lenses (14.3%) compared to other methods.

Conclusions:

• Intraoperative endolaser use and retinal tears are frequent occurrences in secondary IOL surgery.
• These findings highlight the critical need for meticulous vitreoretinal management in patients undergoing secondary IOL implantation.
