1) The study analyzed data from over 11,000 LASIK procedures to understand how long it takes patients to schedule surgery after their initial consultation. 2) They found that slightly over 1/3 of patients scheduled surgery within 2 weeks, while another 25% scheduled within 1 month. However, about 30% delayed scheduling for 1-4 months. 3) When comparing subgroups, contact lens failures were least likely to schedule quickly, while nearsighted patients under 25 tended to schedule the fastest on average. Patients who had surgery more recently also tended to take longer to schedule.

- 1. COVER STORY Decision Time Do certain types of patients take longer than others to schedule LASIK surgery? BY PERRY S. BINDER, MD, MS, AND SHAREEF MAHDAVI R efractive surgeons have long tried to understand why some patients delay their decision to have LASIK after their consultation. Reasons typically involve lingering fear, concern over cost, and/or wait- ing for a specific event to occur. We were curi- ous to understand the impact of time on the decision process and if the delay in signing up for surgery is influenced by demographic or physiological patient characteristics. Our goal was to see if any differences emerged that might prove instructive for surgeons and their Figure 1.

Refractive Error and Age Taken as a whole, patients with myopia and those with hyperopia converted similarly to each other and nearly identically to the overall average. The same finding occured in those younger than 40 years of age compared with those older than 40. When we further distilled the data, we discovered that myopic patients younger than 25 years tended to convert much sooner—45% immediately—than those older than 40 years. This subgroup showed the fastest conversion overall. Figure 2.
