BACKGROUND: Intraocular lens fixation surgery is associated with fluctuations in intraocular pressure. This may be significantly relevant in glaucoma patients. OBJECTIVES: To assess short- and medium-term intraocular pressure control after trans-scleral intraocular lens fixation surgery in glaucoma patients. METHODS: The charts of all glaucoma patients who underwent trans-scleral intraocular lens fixation surgery with at least 6 months follow-up by a single surgeon between the years 2004 and 2017 were reviewed. Primary outcomes were intraocular pressure at 1 day and 6 months after surgery. Secondary outcome measures were hypotensive medication use and the need for further intraocular pressure lowering interventions. RESULTS: Eleven eyes of 10 patients were included in the analysis. Mean follow-up post intraocular lens fixation surgery was 54.6 months. Mean intraocular pressure before, 6 months, and last follow-up after intraocular lens fixation surgery was 15.8 ± 5.3 mmHg (range 10.6-25.3), 13.5 ± 3.8 mmHg (range 8-21, p = 0.2), and 11.8 ± 5.6 (range 6-21, p = 0.09) on a mean of 2.3 ± 1.6, 2 ± 1.6 (p = 0.23), and 1.7 ± 1.5 (p = 0.08) hypotensive medications, respectively. A pressure spike was noted in 5 of the 11 eyes on the first post-operative day (mean spike 15.2 mmHg, range 6-23). Four of 11 eyes in the study (36%) needed additional interventions to control intraocular pressure by the 6-month point. One eye required the addition of two classes of topical medications, one eye required laser trabeculoplasty, and two eyes required trabeculectomy. CONCLUSION: Over a third of glaucomatous eyes required a change in the management of their disease in the early post-operative period. Close follow-up of patients undergoing trans-scleral intraocular lens fixation surgery is warranted.
