Conditions
Interventions
The study will include 30 myopic eyes that will be divided into two groups
Group 1 includes the 30 myopic eyes with IOL implantation using the LENSTAR AL and Holladay 1 formula.
,Group 2 includes the same 30 myopic eyes with IOL power back- calculated using the Koch-Wang mo
