A Study To Show The Relationship Between The Axial Length Of The Eye Ball & IOL (intraocular Lens), To Be Used during Cataract Surgery in Right Eyes in Chhatisgarh Region.

Different anatomical parameters of eye can give us very important values like power of IOL to be used after cataract surgery.In this study we have taken corneal diameter by keratometry & The axial length by ultrasound (A-scan) This is a retrospective study done in a period of one year . Here those cases are taken in to consideration ,those which were diagnosed as Immature or mature cataract & were advised for cataract extraction & IOL implantation of age group 50-80years. Total 200 cases were studied, out of which 100 are male & 100 female & we have studied the the IOL requirement in Right eye only. The data which were collected were the : (1)horizontal & Vertical curvature of cornea which was done by keratometry,(2)axial length which was done by A scan & after applying the SRK-II formula The IOL required was calculated. Then by using various statistical method the result was interpreted. Itwas found that there is correlation between ocular axial length with the power of IOL to be used after cataract surgery. We observed as the axial length increases the power of IOL to be used decreases significantly .The trend remains same for male & female.
