Glaucoma Progression and Development Following Secondary Intraocular Lens Surgery.
Abstract
Background
AND
Objective
This study aimed to investigate glaucoma progression following secondary intraocular lens (SIOL) implantation by surgical approach. PATIENTS AND
Methods
This was a single-center retrospective study of 440 eyes that received SIOL implantation, including scleral-sutured, scleral-fixated, anterior chamber, and sulcus-fixated. Glaucoma progression was defined as new diagnosis, procedure for intraocular pressure (IOP) control, or IOP elevation ≥ 24 mmHg or ≥ 5 mmHg above baseline requiring additional medications. Risk factors were assessed using multivariable analysis.
Results
Mean age at surgery was 71.3 years and 29.3% of patients had prior glaucoma. Overall, 33.2% developed glaucoma progression. Prior glaucoma (hazard ratio 2.08 [95% CI 1.47-2.94], P < .001) and cystoid macular edema (1.63 [1.06-2.52], P = .026) were associated with glaucoma progression on multivariable analysis. There was no difference in glaucoma progression between scleral-sutured, scleral-fixated, anterior chamber, or sulcus-fixated implantation techniques.
Conclusion
Our results suggest that surgeons should use their preferred SIOL implantation technique but closely monitor postoperative IOP.
