Laser in Situ Keratomileusis With New Excimer Laser to Correct Presbyopia in Patients With Hyperopia, Myopia, Emmetropia, or Astigmatism: 6-Month Results
Purpose
To evaluate the 6 months clinical outcomes of LASIK to correct presbyopia using PresbyMAX hybrid.
Methods
Prospective case series. The bilateral presbyopic LASIK for patients was performed using a bi-aspheric ablation profile of the 750 Hz AMARIS laser and the FS200 femtosecond laser for flap creation. The manifest spherical equivalent ranged between +2.25 to -7.0 diopters. Manifest refraction spherical equivalent (MRSE), uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA) were measured preoperatively and 1, 3, and 6 months. The efficacy, safety, and a patient questionnaire on satisfaction were evaluated at 6 months postoperatively.
Results
Fifty-two eyes (28 patients) were included. In the dominant eye versus no dominant eye, the mean MRSE, UDVA, and UNVA was -0.44 D ± -0.45(SD), -1.0 D ± -0.56 (SD), -0.03 logMAR ± 0.14(SD), 0.14 logMAR ± 0.12(SD) and 0.16 logMAR ± 0.09(SD), 0.07 logMAR ± 0.14 (SD), respectively. In the binocular vision, 93 % had an uncorrected reading ability of J2 or better and 79 % had an UDVA of 20/20. Significant improvements of near, distant vision and satisfaction (P<0.01) were observed. However, 78 % of patients had lost minimum 1 line on distance vision, comparing with corrected distance vision.
Conclusion
PresbyMAX hybrid in presbyopic patients provide a good near vision and distance vision as well, resulting in high level of spectacle independence for near and distance vision.
