Cataracts are responsible for 47% of all cases of blindness worldwide. The epidemiological impacts of cataracts are not the same in different countries, and the rates are associated with the prevailing economic conditions. In developed countries with good health care, cataracts account for only 5% of the cases of blindness, whereas the issue is still responsible for 50% of such cases in developing countries. After a brief overview of the historical, clinical, and therapeutic aspects, this article presents an update on the global epidemiological cataract data. It also provides insights into the political, socioeconomic, and cultural factors that adversely affect the availability of health care in developing countries, making cataract a major public health concern and an impediment to development.[1]

The prevalence of cataracts increases with age. As the world's population ages, the incidence of cataract-induced visual dysfunction and blindness is rising, which represents a significant global problem. The challenges include preventing or delaying the formation of cataracts and treating those that occur.[1]

Cataracts can be cured by surgery; however, this option is not equally available everywhere and all surgical methods do not produce similar outcomes. Standard surgical services capable of providing good visual rehabilitation must be made accessible to all in need, regardless of their circumstances. The establishment and sustained delivery of these services requires comprehensive strategies that go beyond a narrow focus on surgical techniques. Changes in governmental priorities, population education, and an integrated approach to surgical and management training are warranted.[2] India is a signatory to the World Health Organization Resolution on Vision 2020. The concerted efforts of all the stakeholders have resulted in a hike in the number of manual small-incision cataract surgeries performed in the country. However, the actual impact of these measures on the elimination of avoidable blindness is unknown.[3]

Various risk factors impact the outcome of cataract surgery.

Each of these risk factors increases the possibility of an adverse outcome during cataract surgery. However, until recently, prediction of the likelihood of a complication during small-incision cataract surgery (SICS) surgery has been based on a subjective assessment of the patient by the surgeon. Various studies have identified individual risk factors that increase the risk of intraoperative complications.[1],[2],[3],[4],[5]

There are scoring systems to predict visual outcome following cataract surgeries cataract[4] which has been validated by multicentric trials in India.[6]

There are cataracts with comorbidities secondary to other ocular diseases that may not have a similar outcome as uncomplicated primary cataracts.

As there are many conditions which may have different visual outcome

The objective is to prognosticate cataracts with comorbidities because of different causes, so outcome may be variable We have tried to develop a mathematical model which may prognosticate Clinical features of different diseases labeled as numbers and resulted score is scaled from small to large and correlated with visual outcome. Visual outcome according to various categories of complicated cataracts studied.

Postuveitis cataracts, traumatic cataracts, cataracts in association with colobomas, cataracts following glaucoma surgeries, cataracts following glaucoma, vitreoretinal surgeries, cataracts with corneal opacities. Cataract with poor zonular support. Other type of complicated cataracts.
