TitleEffect of refractive surgery on ocular alignment and binocular vision in patients with intermittent and manifest strabismus
Abstract Nr.A2025
PurposeTo evaluate the effect of refractive surgery on ocular alignment and binocular functions in patients with intermittent and manifest strabismus.
MethodsEleven strabismic patients underwent refractive surgery. Five patients were myopic, three hyperopic and three anisometropic. Six patients had an anterior chamber lens implantation (Iris Claw) to correct their high myopia (3) and high hyperopia (3). Two patients were operated with diode thermokeratoplasty (DTK) to correct their hyperopia and of the three remaining myopic patients, one had a laser in situ keratomileusis (LASIK), one a laser epithelial keratomileusis (LASEK) and one a photorefractive keratectomy (PRK) procedure.
Three patients had an esotropia and five had a manifest exotropia, three of them with a vertical deviation. Two patients had an intermittent exotropia with binocular vision. One patient had a dissociated vertical deviation (DVD).
The dominant eye was operated first, aiming for emmetropia, in all patients of whom both eyes were treated.
ResultsIn all ametropic patients the ocular alignment and binocular functions remained unchanged. Only in the two high anisometropic patients the manifest deviation became intermittent or latent and fusion and stereopsis were restored.
ConclusionRefractive surgery did not change the ocular alignment. Binocular functions were only improved in the high anisometropic patients. None of our patients had post-operative diplopia, binocular vision problems or dominance problems
