Abstract Details


To evaluate the clinical outcomes of laser in situ keratomileusis to correct presbyopia using PresbyMAX hybrid software with a 750 Hz scanning-spot laser system.


Happy Eye 21 Private Hospital, Gwang-Ju, South Korea.


Patients with Presbyopia including myopia, hyperopia or astigmatism (spherical equivalent +2.25 to -7.0 diopter [D]) and an estimated residual bed thickness of 300㎛or better using a tetra-aspheric ablation profile of the 750 Hz scanning-spot laser and the FS200 femtosecond laser for flap creation. All patients were followed of 3 months postoperatively. The main outcome measures were manifest refraction, astigmatism, uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), predictability and, patients satisfaction at 3 months.


: Forty-two eyes (21 patients) were included. At 3 months, the dominant eye(DE) mean UDVA and non-dominant (NDE) mean UDVA was -0.01 log MAR ± 0.09(SD) with ninety five percent having a UDVA of 0.2 log MAR or better and 0.1 log MAR ± 0.09(SD), with ninety five having UDVA 0.2 log MAR or better, respectively. Regarding to the binocular UNVA, Ninety Five percent had an uncorrected reading ability of J3 or better, with 52.4% showing J1 and Nine Five percent were fully independent of reading glasses. One patient was required a retreatment in the both eye to enhance UNVA. Ninety percent had a satisfaction they got the procedure.


At 3 months, PresbyMAX hybrid ablation profile in presbyopic patients provide a high level of spectacle independence for near and distance vision in Korea.
