Abstract
Purpose: :
To evaluate the refractive outcome of hyperopic LASIK using the VISX Star 4 Excimer Laser and manual Moria microkeratome.
Methods: :
This retrospective study analyzed 28 eyes of 15 patients with preoperative hyperopia treated from March 2006 to March 2007. There were 8 males and 7 females with an average age of 58 years old. Nine patients were treated for monovision. Patients were followed for 12 months postoperatively. Every patient underwent preoperative ophthalmic tests that included a thorough slit lamp exam, keratometry, Orbscan, pachymetry, cycloplegic refraction, and recorded uncorrected and best-corrected visual acuity. The LASIK was performed using the VISX Star 4 excimer laser. The corneal flaps were 160 microns thick and were created using the Moria microkeratome.
Results: :
Preoperative hyperopia ranged from +0.25 to +5.25D with astigmatism range up to +1.25D. The mean preoperative sphere was +2.2D. Twenty-two eyes completed the one month follow up and thirteen eyes completed the three month follow up. Twenty eyes completed the six month follow up exam. At six months, of those eyes treated for distance vision: 1 had 20/15 vision, 8 had 20/20, 2 had 20/30, and 1 had 20/40 vision. Of those for near vision: 5 had J1+, 1 had J1, 1 had J2 and 1 had J3 near visual acuity.Sixteen eyes completed the one year follow up exam. Of those eyes treated for distance vision: 1 had 20/15 vision, 7 had 20/20, 3 had 20/25 vision. Of those for near vision: 2 had J1+, 2 had J1, and 1 had J3 near visual acuity.At one year, 100% of patients had uncorrected vision 20/25 or better for distance. Eighty-percent of patients had J1 or better near vision at one year. No patients lost best corrected visual acuity. No complications occurred.
Conclusions: :
Our results in hyperopic LASIK are encouraging. Refractive stability occurred and was maintained for one year.
