Abstract
Purpose: :
To describe a new solution for post laser in situ keratomileusis (LASIK) patients with sub optimal results, including loss of best corrected visual acuity, poor contrast, and starbursts/halos at night.
Methods: :
Myopic LASIK (Visx S4) was performed on a 65 year old female with a monovision refractive goal. The surgery was eventful for an irregular flag in the distance seeing eye and a subsequent epitheliopathy that left the patient 20/30 uncorrected and 20/25 with a refraction of –0.25–1.00 x 010 as measured six months post–operatively. The patient had complaints of poor vision, especially at night and a lack of contrast. Wavefront abberometry (ZView aberrometer, Ophthonix, Inc.) was performed and wavefront guided spectacles were made for the patient (IZon lenses, Ophthonix, Inc.) to correct for the patient's higher order aberrations and to neutralize her monovision.
Results: :
The patients best corrected vision improved from 20/25 to 20/20–1 in the effected eye and her subjective complaints of poor night vision and lack of contrast were much reduced.
Conclusions: :
Wavefront guided lenses are an effective solution for the LASIK patient with sub optimal results and subjective complaints.
