Re: Laser refractive eye surgery

Cataract constitutes the first cause of reversible blindness in the world, comes from one of the most frequent surgeries of the previous segment and in turn it has been one of the more controverial themes in ophthalmology in the last 50 years (1).

We decided to study the frequency and diffusion of cataract. Most cases are related to the normal process of aging and the increment of life expectancy. Currently, more than 25 % of the Cuban population is older than 60 years (2). This pathology tends to increase in the next years, treatment is surgical, and it is very successful for resetting vision (3).

Four hundred seventy patients were studied in Sancti Spíritus, 56,7 % of them male and 43,2 % female.
Of the studied patients we gathered their preoperative sharp sight, and we found out that 41,06 % had their vision between 0,1 and 0,3; 37,65 % can only see their fingers, 19,57 % had diffuse vision and 1,70 %, luminous perception.
Three months after the operation, 64,89 % had vision of more than 0,7, 25,53 % between 0,4 and 0,7 of vision and 8,29 % between 0,1 and 0,3, which confirms the magnificent visual results in our patients.
