Abstract Details

Purpose:

Wavefront analysis aims to measure aberrations in the eye, often before and after surgeries. The Hartmann�â�€�“Shack instrument is an outgoing reflective aberrometer that uses a laser light source. The authors aimed to evaluate changes in aberrations of the eyes with macular irregularity by comparing with the fellow normal eyes.

Setting:

Eye Research Center and Department of Ophthalmology, Khatam-al-Anbia Eye Center, Mashhad University of Medical Sciences, Mashhad, Iran Eye Research Center, Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran

Methods:

In a prospective study, the authors evaluated both eyes of patients with unilateral acquired foveal lesion by ZyWave (ZyWave; Milwaukee, WI) aberrometer. Eighteen eyes of 9 patients with a mean age of 32 years were examined.

Results:

After exclusion of two cases with central serous chorioretinopathy (due to smooth macular surface), a statistically significant increase in higher-order aberration in the involved eyes compared with the normal fellow eyes (P = .043) was found. There was also a statistically significant increase in horizontal trefoil in the involved eyes compared with normal eyes (P = .04).

Conclusions:

This fellow eye study shows that macular irregularity might increase high-order aberrations measured by the Hartmann�â�€�“Shack aberrometer.
