A Comparative Study between Conventional LASIK and IntraLASIK Surgeries Based on Sigma Quality Levels

IntraLASIK is the most recent surgery for corneal refractive surgery and has emerged as an alternative to LASIK surgery. However, IntraLASIK surgery comes at a higher cost to the patient and also requires additional investment to any eye center willing to practice it. This study identifies the complication profiles of conventional LASIK and IntraLASIK surgeries. The incidences of the complications in each surgery are individually presented in terms of sigma quality levels to contrast the efficiency. Having led to fewer complications, the process sigma level of IntraLASIK is found to be higher than the level of LASIK. This suggests that IntraLASIK is a more efficient refractive surgery than LASIK.
