To evaluate the effect of reduction of postoperative intraocular pressure on refractive error after LASIK
Patients undergoing LASIK were randomly assigned to receive 0.5% timolol in one eye in addition to routine antibiotic-steroid regimen. Timolol was prescribed from week 1 to 3rd month postoperatively. We evaluated refraction at the end of 1 week, 1 month, 3rd month and 6 months postoperatively.
Forty-three patients were included. There was no significant difference in the amount of myopia at baseline (5.51D vs 5.41D), 1 week (0.08 D vs 0.01D), 1 month (0.08 D vs 0.11D), 3 months (0.08 D vs 0.04D) and 6 months (0.03D vs 0.02D) with and without timolol respectively (p ≥0.141). The mean IOP was significantly lower at 1 and 3 months postoperatively in eyes receiving timolol (p<0.001).
The use of IOP-reducing drops did not have a significant effect on residual myopia after LASIK.
