Brimonidine tartrate 0.15% drops to reduce low post-LASIK residual myopia: A retrospective study.
Abstract
PurposeResidual myopia following Laser-assisted in situ keratomileusis (LASIK) surgery poses a significant concern, with existing literature extensively detailing the use of timolol for treatment. This study aims to assess prediction factors for brimonidine tartrate 0.15% (Alphagan-P) response on post-LASIK residual myopic refraction reduction.MethodsThe study included consecutive patients who received Alphagan-P during their follow-up for post-LASIK residual myopia.ResultsWe included 61 patients (55% male) with a mean age of 35.18 ± 10.13 Alphagan-P Treatment started at a mean of 4.94 ± 5.64 months after surgery for residual myopia of -0.53 ± 0.71D. Comparison analysis of patients who responded (n = 32, 51.6%) to patients who did not (n = 30, 48.4%) shows that responders were older (38.1 ± 9.1 vs. 32.3 ± 10.3, p = 0.03), had higher baseline myopic Spherical equivalent (SE, -0.82 ± 0.65 vs. -0.26 ± 0.66 p ConclusionsAlphagan-P can reduce up to 0.5D of post-LASIK residual myopia in roughly 50% of subjects. This treatment might be recommended to fine-tune outcomes for low residual myopia.
