Beyond the First Cut: Evaluating LASIK Reoperation Trends

The aim was to evaluate the reoperation rate in laser-assisted in situ keratomileusis surgery (LASIK) and to identify the underlying factors that necessitate retreatment.

A retrospective study was conducted at a tertiary eye-care centre in central India, which included 288 eyes that underwent LASIK between June 2020 and April 2023, with nine eyes of nine patients who underwent reoperation. Factors included were demographic data, type of reoperation, that is, flap striae correction by its re-lifting, correction of a dislodged corneal flap, clearing debris of diffuse lamellar keratitis, and treatment for over- or under-correction.

Nine out of nine patients underwent reoperation of 288 eyes. The re-surgery rate in our study was 3.12%. Six patients were male, and three were female. The age group of patients was 21-30 years (±2). All patients were from urban areas. The reoperation included re-lifting a dislodged corneal flap (n=3, 1.04%), flap striae correction (n=2, 0.69%), clearing the debris of diffuse lamellar keratitis (n=2, 0.69%), and treatment for over (n=1, 0.35%), or under-correction (n=1,0.35 %).

There was no significant gender difference in reoperation rates, although six of the nine cases involved males. This observation warrants further exploration into potential behavioral or occupational factors that might predispose males to flap-related complications.The retrospective design of this study and its reliance on data from a single surgeon may limit the generalizability of the findings. Multi-center studies with larger sample sizes could provide a more comprehensive understanding of reoperation rates and associated factors. Future research should also explore patient-reported outcomes and satisfaction scores to contextualize the clinical findings better.Advancements in refractive surgery techniques, such as the adoption of small incision lenticule extraction (SMILE), could also be evaluated for their impact on reoperation rates. Moreover, the role of artificial intelligence in refining patient selection and predicting surgical outcomes represents an exciting avenue for enhancing the safety and efficacy of LASIK procedures.

This study highlights key factors driving LASIK reoperations and emphasizes that addressing complications and leveraging emerging technologies can significantly improve patient outcomes and satisfaction.
