LASIK Compared with Small-Incision Lenticule Extraction
Even a small delay in corneal optical recovery after small-incision lenticule extraction might lead to reduced contrast sensitivity and patient-reported visual issues 1 week postoperatively, according to a prospective case series involving 92 eyes of 46 individuals.
Participants were slated for bilateral small-incision lenticule extraction (n=46) or LASIK (n=46). Investigators looked at standard refraction and visual acuity; contrast sensitivity; aberrometry; and patient-reported quality of vision and overall satisfaction 1, 7, and 30 days postop. Among the results:
- Contrast sensitivity was better in the LASIK group at 1 and 7 days, but not at 30 days.
- There were no differences in visual acuity, efficacy, or safety at any time point.
- Objective scatter index assessed was better after LASIK at 1 day, but statistical significance did not hold up at the other time points.
- Patient-reported quality of vision was significantly better in the LASIK group at 7 days.
- Satisfaction was the same in both groups at all time points.
- A significant link was seen between contrast sensitivity and aberrometry in both groups throughout the study.
