Evaluation of Vision Changes Using SRK / T Formula in Cataract Senilis Performed Phacoemulsification

Objective The accuracy of biometric examination is very useful in cataract surgery to reduce refractive errors and best vision results. After the operation, it is expected to achieve target vision as emmetropia. Method The total of 45 senile cataracts performed by phacoemulsification. Power IOL using Formula SRK/T, axial length, and anterior chamber depth measured by using Optical Biometry ( IOL Master 500) at Medan Baru Eye Centre Hospital from January to February 2018. After phacoemulsification each visual acuity of the patient was being examined then performed follow-up on days to 7, 14, and 30 post operative. Results The number of cataract patients performed 45 phacoemulsification, visual acuity result is better in medium axial length as much as 15 eyes, compared to short and long axial length. Conclusions There is no significant correlation between changing of vision and short, moderate and long axial length using the SRK / T formula.
