Purpose

To evaluate the long-term safety, effectiveness, and stability after topography-guided ablation treatment (T-CAT) LASIK for the correction of myopia and myopic astigmatism.

Setting

Clínica Oftalmológica Dr. Horácio Correia, Bragança, Portugal.

Methods

This was a retrospective, non-comparative case series study of 25 patients (40 eyes) with low to moderate myopia with or without astigmatism who underwent topography-guided custom LASIK with the Wave-Light EX500 excimer laser platform (Alcon Laboratories, Inc., Fort Worth, TX). The customized treatment plan was based on Topolyzer Vario topography system (Alcon Laboratories, Inc.) data. The patients were evaluated at 6 months, 1 year, 2 years, 3 years and 5 years after the procedure.

Results

The surgery significantly reduced the manifest refractive spherical equivalent (MRSE), sphere, and cylinder (P < .05) during the follow-up. The visual and refractive outcomes showed to be stable during the follow-up of the study. Compared with the preoperative corrected distance visual acuity (CDVA), 15 (37.5%) of 40 eyes gained one or more lines of postoperative uncorrected distance visual acuity at the 5th year visit. There were no cases that presented loss of one or more lines of CDVA during the study. Fifteen patients (20 eyes) reported symptoms related to dry eye during the first 6 months after the procedure.

Conclusions

The T-CAT custom LASIK provided safe, effective and stable outcomes for treating patients with low to moderate myopia with or without astigmatism.
