Molecular genetics have contributed greatly to our knowledge of inherited ocular malformations. Basic and clinical science was limited to a description and classification of phenotypes based on morphology, biochemistry and physiology. Progress was severely hampered by the death of genetic information.Vision loss in eye is mainly due to some changes or environmental factors affecting the lens of eye. The most important risk factors age and hereditary are associated with different types of cataract. While the hereditary factor is self-explanatory, including age assist as an alternative for a number of possible risk factors, the effect of which is cumulative. Human visual system consists of two parts, eye acts as image receptor for capturing light which is then transmitted to image processing centers in the brain. Any defect in the visual pathway leads to vision loss. A retrospective analytical study was performed during October 2013 and April 2014 on all congenital cataract cases in Lahore seen in the CC unit of the Layton Rahamatullah Benevolent Trust (LRBT) hospital. The aim of this research was to evaluate the incidence of lens extraction and blindness in patients of CC.
