Supracor LASIK treatment of hyperopic and myopic presbyopes: a comparative study

Abstract

Background Supracor is a relatively new technique that has been approved for hyperopic presbyopia correction; however, till now, no published studies have evaluated the performance of supracor in myopic patients with presbyopia. Objective The aim of this study was to compare the results of supracor treatment of presbyopia between hyperopic and myopic patients. Patients and methods The study included two groups: hyperopic group and myopic group. Complete preoperative examination consisted of cycloplegic and manifest refraction, spherical equivalent (SE), binocular uncorrected and corrected distant visual acuity (UCDVA and CDVA), binocular uncorrected and corrected near visual acuity (UCNVA and CNVA), measurement of higher order aberrations, and the determination of the dominant eye using hole-in-the card test. Patients were examined at the first day, third day, 1 month, 3 months, and 6 months postoperatively. UCDVA, CDVA, UCNVA, CNVA, higher order aberrations, and SE were measured, and all complications were recorded. Furthermore, patient’s satisfaction was documented by a detailed questionnaire. All data were collected, analyzed, and compared between the two groups. Results The study included 20 hyperopic and 19 myopic patients. There were no statistically significant differences (P>0.05) between the two groups regarding postoperative UCDVA, CDVA, UCNVA, CNVA, SE, spherical aberrations, and complications. However, there was a statistically significant difference (P<0.05) between the studied groups regarding patient satisfaction at 1 month, 3 months, and 6 months postoperatively (which was higher in patients with hyperopia), with a significant increase in patient satisfaction in those with hyperopia over time. Conclusion Supracor was found to be effective, predictable, and stable technique in the management of presbyopia in both patients with myopia and those with hyperopia, with similar results in the two groups except for patient satisfaction, which was higher in those with hyperopia.
