Objective To evaluate safety and efficacy of SUPRACORTM technique in treating hyperopic presbyopia. Methods It was a retrospective case-series study. Seventy-two eyes of 36 patients with hyperopic presbyopia a new centered multifocal aspheric Presby LASIK, and followed 24 months postoperatively. Uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), diopter, central corneal curvature, intraocular pressure, central corneal thickness,corneal deformation amplitude and patient satisfaction (questionnaire) were measured. Data were analyzed using paired t test, repeat measured ANOVA, Friedman rank sum test. Results The UDVA of 24 months postoperative improved compared with preoperation [0.1(0.5- -0.1)logMAR vs. 0.2(1.0-0.0)logMAR, Z=-2.59, P<0.01]. The UNVA of 24 months postoperative improved compared with preoperation [0.2(0.8- -0.1)logMAR vs. 0.55(1.3-0.3)logMAR, Z=-7.14, P<0.01]. The spherical dioptor and cylindrical dioptor were -0.25(-1.25- +1.25)D and -0.24(-1.25-0.00)D respectively postoperative. Mean power of the 3 mm corneal central increased (43.97±1.67 D vs. 43.33±1.51 D, t=16.85, P<0.01). Postoperative corneal deformation amplitude is greater than the preoperation (F=4.88, P<0.01). The score of life quality questionnaire was 80±16 with at 6 months postoperation. Conclusion SUPRACORTM Presby LASIK could decrease the presbyopic symptoms and correct far distance refraction, offering spectacle-free vision in daily life in most of the treated patients.
