Childhood cataract is cataract that occurs at birth or in childhood. [1] It may be congenital or acquired. Congenital cataracts are defined as the presence of lens opacification during childhood. [2] About 1.14 million children in the world are blind. [3] Cataracts are the leading cause of blindness in children. [4]
Treatment options depend on the severity of the condition. For children under the age of two years old whose vision is affected by the cataracts in both eyes, surgical options include intraocular lens implantation or a lensectomy. [2] Congenital cataracts are considered to be a significant cause of childhood blindness.
Early symptoms of cataract may be improved by wearing appropriate glasses; if this does not help, cataract surgery is the only effective treatment. [4] Surgery with implants generally results in better vision and an improved quality of life: however, the procedure is not readily available in many countries. [4] [11] [12] [13]
At some point—usually as you enter middle age—most people develop this eye condition, which is a clouding of the eye’s lens that can get progressively worse and impair your vision.
This method of surgery reduced the need for an extended hospital stay and made out-patient surgery the standard. [8] In 1985, Thomas Mazzocco developed and implanted the first foldable IOL. Graham Barrett and associates pioneered the use of silicone, acrylic, and hydrogel foldable lenses, making it possible to reduce the incision width. [ 7 ]
If this does not help, surgery to remove the cloudy lens and replace it with an artificial lens is the only effective treatment. [1] Cataract surgery is not readily available in many countries, and surgery is needed only if the cataracts are causing problems and generally results in an improved quality of life. [1] [11] [4] [12]
The study also shown a significant correlation between gross national income per capita and cataract-surgery rate in the countries involved. [30] In a study published in 2014, the weighted-mean regional surgery rate was found to have increased by 70% from 2005 to 2012, rising from 1,562 to 2,672 cataract surgeries per million inhabitants.

A lens regeneration technique was trialled in a collaboration between Sun Yat-sen University and University of California, San Diego which was published in 2016. [8] The capsule of the lens was pierced with a smaller cut than in conventional cataract surgery – just 1–1.5 mm – and drained of its contents clouding the vision causing cataracts.
