Abstract :
Purpose:To compare the pupil diameter measurements in skotopic, mesopic and photopic illuminations of patients of myopia and hyperopia.Materials and methods:The records of myopia and hyperopia patients who applied for keratorefractive surgery between 2012-2013 were analyzed. Pupil diameter measurements were performed preoperatively by infrared pupillometer integrated within a Scheimpflug camera combined with Placido corneal topography (Sirius). Patients’ right eyes pupil diameter measurements in skotopic, mesopic and photopic illuminations were used. The groups were compared with the Mann-Whitney U test for continuous variables and with the χ² test for categorical variables.Results:Median values of scotopic, mesopic and photopic pupil diameters were found in myopic group consisting of 60 patients, respectively, 6.5 (4.3 to 7.6) mm, 6 (3.4 to 7.5) mm and 4.4 (1.9 to 7 ) mm and age - gender matched in hyperopic group consisting of 31 patients, respectively, 5.8 (4.2 – 7.2) mm, 5.4 (2.8 – 6.7) mm ve 3.9 ( 2.4 – 6) mm. In myopia group, pupil diameter measurements were found to be statistically significantly larger in allilluminations (p=0.001), although statistical significance was less in photopic lighting (p 0.049).Conclusion: We believe that it would be useful to keep surgical ablation diameter greater in myopic patients to reduce the risk of glare and halo in keratorefractive surgeries when compared with hyperopia patients.
