Patients who underwent either SMILE or LASIK surgery experienced high efficacy and safety, but SMILE patients experienced higher refractive power correction in the peripheral cornea, according to a study.
The retrospective case-matched study included 34 eyes of 23 patients who underwent SMILE and 34 eyes of 24 patients who underwent LASIK. At 3 months postop, safety, efficacy and predictability were compared between the two groups.
“This is a first study truly comparing refractive power correction efficiency between SMILE and LASIK groups after adjusting the optical zone. We revealed the SMILE group showed higher efficiency in correction at the peripheral cornea than the LASIK group,” Takashi Kojima, MD, PhD, co-author of the study, told Healio.com/OSN.
According to the study, 82.35% of SMILE patients and 85.3% of LASIK patients achieved 20/13 or better uncorrected distance visual acuity. Additionally, 97.06% of SMILE patients and 100% of LASIK patients achieved 20/13 or better corrected distance visual acuity. The differences were not statistically significant.
However, the SMILE patients experienced significantly higher maintenance ratios of corneal refractive power changes at the peripheral points compared with LASIK patients (P < .05). – by Robert Linnehan
