Abstract Details
Purpose:
To analyze corneal and refractive stability of hyperopic laser-assisted in situ keratomileusis (LASIK) with and without concurrent prophylactic high-fluence cross-linking (CXL).
Setting:
Ophthalmology Department, Faculty of Medicine, Minia University, Minia, Egypt.
Methods:
Interventional prospective consecutive comparative case control series of cases;
50 eyes of 25 patients with mean age 35.6 ± 12.1 with hyperopia or hyperopic astigmatism underwent customized LASIK with concurrent prophylactic high-fluence cross-linking in right eye (group A) and customized LASIK only in left eye (group B). Cases with hyperopia +1D to +6D or hyperopic astigmatism up to 4D were included in the study. Main outcome measures were uncorrected visual acuity, manifest refractive spherical equivalent (MRSE), cycloplegic refractive spherical equivalent (CRSE), keratometric measurements and spherical aberrations at 4 mm and maximum pupil and their evolution along 2 years postoperatively.
Results:
UCVA, MRSE, CRSE, medium keratometry, spherical aberration at 4 mm and maximum pupil ware significantly changed at 3 months, 1 year and 2 years period postoperatively compared to preoperative values in both groups, and remained stable in group A through follow up period.
In group B; UCVA was significantly better at 1 year than 3 months (P value 0.005)
UCVA was significantly better in group A than group B at 3 months with P value 0.02.
Safety and efficacy are better in group A than group B at 3months, 1 year and 2 years.
Conclusions:
Safety, efficacy and visual stability are better in hyperopic LASIK with concurrent prophylactic high-fluence cross-linking.
