Objective:
To evaluate the visual and refractive outcomes of LASIK, PRK, phakic IOL, and Supracor as treatment for errors of refraction, including presbyopia, performed at a private eye center.
Methods:
This is a retrospective, single-center, single-surgeon study that reviewed the surgical outcomes of patients who underwent LASIK, PRK, phakic IOL, and Supracor from January 2010 to December 2014. Main outcome measures were postoperative uncorrected and corrected distance, intermediate, and near visual acuity (for Supracor), and mean manifest-refraction spherical equivalent (MRSE) of patients who had at least 1 month follow up. Complications and enhancements were analyzed independently.
Results:
Data were analyzed from 1,366 eyes of 771 patients. LASIK was the most commonly performed procedure (68%), followed by PRK (18.3%), Supracor (10.2%), and phakic IOL (3.7%). The postoperative mean MRSE at 1 month for LASIK, PRK, and phakic IOL were -0.08 ± 0.36, +0.06 ± 0.52 and -0.11 ± 0.44, respectively. The mean postoperative logMAR uncorrected distance visual acuity (UDVA) at 1 month for LASIK, PRK, and phakic IOL were 0.02 ± 0.10, 0.07 ± 0.12, 0.001 ± 0.09, respectively. In the Supracor group, the mean preoperative and postoperative spherical equivalent were +1.12 ± 0.8 and -0.76 ± 0.62, respectively. The mean postoperative logMAR UDVA and uncorrected near visual acuity (UNVA) for Supracor were 0.24 ± 0.19 and 0.02 ± 0.08, respectively. The most common postoperative complication was symptomatic dry eye (13%). Regression and off-target outcomes occurred in 24 (1.8%) and 13 eyes (1%), respectively. Overall enhancement rate was 2%.
Conclusion:
LASIK remained to be the most common refractive procedure, with femtosecond laser-created flap becoming the norm. Refractive and visual outcomes showed good efficacy with all the refractive procedures. Complication and enhancement rates were low.
