Abstract
Purpose :
Glaucoma and cataract are the leading cause of vision loss in elderly patients. The use of trifocal lenses has been proscribed in the field of glaucoma as alterations of contrast sensitivity had been described. We present a study in which we analyze performance of patients with glaucoma before and after cataract surgery with trifocal lens implant.
Methods :
We present a longitudinal, prospective and analytic study. Inclusion criteria were: presence of cataract, glaucoma suspect or mild glaucoma, previous examination of visual field and nerve fiber layer oct. Exclusion criteria were: severe glaucoma damage, concomitant ocular diseases, previous ocular surgeries and more than 1 diopter astigmatism.
We examined near and far visual acuity ,contrast sensitivity , and nerve fiber layer at baseline, first day, seventh day, 2 weeks and 1 month after surgery.
Results :
9 eyes of 5 patients were included between 66 and 87 years with mean age of 73.2 ± 7.6. Visual acuity had a clinical improvement of 2 lines in far sight and 6 lines in near sight. No statistical significative changes were observed in visual fields standard deviation (p=0.37), fiber nerve layer thickness (p=0.12) nor contrast sensitivity at the baseline and postsurgery results.
Conclusions :
The use of AT LISA can be an alternative for cataract surgery in mild glaucoma or glaucoma suspect as it doesn’t affect contrast sensitivity and follow up studies for glaucoma.
