| description | Pur po se: Evaluation of the corneal high-order aberrations and visual quality changes after application of silicone hydrogel contact lenses
in patients with corneal opacities due to various etiologies.
Ma te ri al and Met hod: Fifteen eyes of 13 patients with corneal opacities were included in the study. During the ophthalmologic examination
before and after contact lens application, visual acuity was measured with Snellen acuity chart and contrast sensitivity - with Bailey-Lowie Charts
in letters. Aberrations were measured with corneal aberrometer (NIDEK Magellan Mapper) under a naturally dilated pupil. Spherical aberration,
coma, trefoil, irregular astigmatism and total high-order root mean square (RMS) values were recorded. Measurements were repeated with
balafilcon A lenses (PureVision 2 HD, B&L) on all patients.
Re sults: Patient age varied between 23 and 50 years. Two eyes had subepithelial infiltrates due to adenoviral keratitis, 1 had nebulae due
to previous infections or trauma, and 2 had Salzmann’s nodular degeneration. We observed a mean increase of 1 line in visual acuity and 5
letters in contrast sensitivity with contact lenses versus glasses in the patients. Mean RMS values of spherical aberration, irregular
astigmatism and total high-order aberrations decreased significantly with contact lenses.
Dis cus si on: Silicone hydrogel soft contact lenses may improve visual quality by decreasing the corneal aberrations in patients with corneal
opacities. (Turk J Ophthalmol 2012; 42: 97-102 |
