 The incidence of glaucoma during the first 5 years

YearIncidence of aphakic glaucoma
Percentage of eyes after unilateral or bilateral lensectomy and 95% CIPercentage of infants after bilateral lensectomy and 95% CI
Model l0, constant hazard model with constant incidence. The incidence remained statistically constant for the first 5 years.
Model l1, piecewise constant hazard model with variable incidence. (*The incidence figures in year 1 do not include two eyes (table 1, patients 1 and 3) with glaucoma responded to anterior vitrectomy without need for long term ocular hypotensive medication.)
