Abstract Details

Purpose:

to analyze the diplopia in patients after cataract surgery.

Setting:

National Medical Research Center "S.Fyodorov Eye Microsurgery Federal State Institution", Irkutsk branch, Russia

Methods:

We analyzed the data of 31 patients with complaints on diplopia after phacoemulsification with IOL implantation. The monocular diplopia was revealed in 7 patients. The binocular diplopia was in 23 cases. A combination of monocular and binocular diplopia (polyopia) was estimated in 1 case. The corneal and total optical abberations, the IOL position, the binocular activity were examined.

Results:

The reasons of monocular diplopia were: the post-LASIK cornea apex decentration (n=1), the actual cornea zone deformation after radial keratotomy (n=5), the rotation of toric IOL (n=1). The binocular diplopia was developed due to the acquired anisometropia (n=4), the heterophoria decompensation (n= 11), the ignored pre-surgery extraocular muscle paresis in patients with mature cataract (n=7), the extraocular musculopathy after periocular anesthesia (n=1). The polyopia was in patient with heterophoria decompensation and history of bilateral radial keratotomy (n=1).

Conclusions:

The monocular diplopia was the result of high level of low-order aberrations, in this case the intraocular aberrometry, the corneal topography, detection of IOL position had high informative diagnostic impact. The low level of disparate fusion was revealed in all cases of binocular diplopia.
