Study parameters included the procedure performed, surgical location, manifest refraction (MRSE), Pentacam D value, anterior chamber depth, and central pachymetry.Results: Overall, 1,866 eyes of 933 patients were included. LASIK was the most common refractive surgery procedure (65.5%), followed by ICL (13.3%), PRK (12.1%), and KLEx (8.6%). Of all the procedures, 59.4% were performed in a laser suite, 26.3% in an in-office operating room (OR), 13.8% in an ambulatory surgery center (ASC), and 0.5% in a hospital OR. The mean MRSE was − 4.36 D. Among laser vision correction procedures (LASIK, PRK, and KLEx), 43.6% had low myopia (MRSE range: − 0.25 to − 3.00 D), 43.1% had moderate (− 3.01 to − 6.00 D), and 13.3% had high myopia (> 6.00 D). Among all ICL cases, 3.6%, 21.0%, and 75.4% were performed in low, moderate, and high myopes, respectively. Among eyes that underwent LASIK or KLEx, 2.8% had thinner corneas (central pachymetry < 500 μm), which was significantly lower than 12.4% of eyes undergoing PRK (p< 0.001) and 11.7% of those undergoing ICL surgery (p< 0.001).Conclusion: The study’s findings help to understand and better define the refractive surgery choices made by patients and surgeons. LASIK contributed to almost two-thirds of the refractive surgery procedures.Keywords: refractive surgery trends, phakic IOL, laser vision correction, implantable collamer lens, office-based surgery
