Purpose To evaluate the outcomes of Lasik with
aspheric ablation profiles and a micro-monovision
protocol for correction of presbyopia in pseudophakic
patients.
Patients and methods This study included 50 pseudophakic eyes of 25 patients. Full ophthalmic examination, dominant eye tests and tests for tolerance of
anisometropia (1 or 2 diopters) were done preoperatively. All cases were treated by Lasik with laserblended vision technique. The dominant eye corrected
to plano, and the nondominant eye corrected with near
add in the range from 1.50 to 2.00 diopters. Excimer
laser ablation was done using the MEL90 with a
250-Hz pulse rate (Carl Zeiss Meditec, Jena, Germany, Triple-A profile, Lasik mode). The follow-up
period was 6 months with visits at 1, 3 and 6 months
postoperatively.
Results The mean postoperative uncorrected distant
visual acuity at 1 month (0.74 ± 0.11) was significantly lower than the preoperative level (0.84 ± 0.14)
(p.001). But it improved at the 3rd (0.80 ± 0.09)
and 6th months (0.82 ± 0.10) with no significant
difference with the preoperative level (p = 0.344).
The mean uncorrected near visual acuity was
significantly higher at the 1st (2.94 ± 1.63 J), 3rd
(2.95 ± 1.82 J) and 6th (2.92 ± 1.83 J) postoperative
months than the preoperative level (2.26 ± 1.48 J)
(p.001). Insignificant change in stereopsis was
found after surgery (p = 0.849). The micro-monovision was well tolerated (95.8%).
Conclusion Lasik with aspheric ablation profiles and
a micro-monovision protocol is an effective option for
presbyopia correction in pseudophakic patients |
