Abstract
Purpose:
To report the incidence of glaucoma & visual axis opacification (VAO) after unilateral cataract surgery in infancy with a primary IOL at the time of cataract surgery versus secondary IOL later in childhood
Methods:
Study population: Infants operated for monocular cataract before seven months of age. Inclusion criteria: Unilateral congenital cataract, and Corneal diameter ≥ 9 mm. Exclusion criteria: acquired cataract, persistent fetal vasculature, glaucoma and duration of follow up less than 5 years. Two groups were formed: group (1): primary IOL, group (2): secondary IOL
Results:
Median age at cataract surgery was 2.7 months for group 1 (n=13) and 1.89 months for group 2 (n=13)(P=0.3). Secondary IOL implantation occurred in group 2 at a median age of 4.9 years. Age at last follow-up was 10.71 and 8.7 years, respectively. (P=0.17). Glaucoma was diagnosed in 15.4% & 23.0% of eyes in group 1 & 2 respectively (p>0.05). VAO developed in 38% in group 1 and, 46 % in group 2 (P>0.05). VAO in group 2 developed before the IOL implantation and no VAO developed later, after IOL implantation.
Conclusions:
We found no significant differences in the incidence of glaucoma & VAO between primary & secondary IOL groups after 5 or more years of follow up.
