·         Cataract                                 : 62.60%

·         Refractive errors                      : 19.70%

·         Glaucoma                               : 05.80%

·         Posterior segment disorder       : 04.70%

·         Surgical Complication               : 01.20%

·         Corneal blindness                    : 0.90%

·         Posterior capsular opacification : 0.90%

Q

What are the reasons for prevalence of blindness in India


The major reasons are:

·         The overall increase in the size of the population

·         The life expectancy for both males and females has steadily increased

·         A major proportion of aged population in rural areas have poor access to eye care facilities in India

·         Inadequate availability of trained health personnel. Further, the services of available ophthalmic surgeons in the country are not being adequately utilized. Many ophthalmologists are purely working in administrative jobs and similar proportion is posted at peripheral units with no ophthalmic equipments.

·         The poor nutritional status of mothers and young children predisposes the pre-school children to nutrition blindness. However, it is heartening to note that prevalence of nutritional blindness has decreased tremendously over the past few years

·         Adverse environmental conditions and domestic unhygienic conditions predispose to high infection rates

·         Lack of community awareness and poor health seeking behavior

·         The prevalence of myths and misconception about surgeries hamper the achievement of programme objectives

Q

What is cataract


Cataract is a term applied when the human lens loses its transparency and become opacified. Hence the light cannot pass through the lens so as to produce a clear image

Q

·        Eye removal takes only 10-15 minutes and leaves no scar or disfigurement of the face

·         Only the cornea is transplanted for all practical purpose and not the entire eyeball. However, other parts of eye is used for research and education purpose.

·         Eye donation gives sight to two blind persons. One blind person is given one eye.

·         The donated corneas are transplanted to patients eye who are waiting list in accordance with the priority based on guidelines to avoid malpractices.
