SRK formula used to calculate power of IOL is ( A ⇒ IOL constant ,K ⇒corneal curvature, L  ⇒ axial length of eyeball): (A) A - 2.5k - 0.9 L, (B) A - 2.5L - 0.9 k, (C) 2.5A - L- 0.9K, (D) L - 0.9L - 2.5K
Answer is B. SRK formula to calculate power of IOL
Power = A → IOL constant
L ⇒ axial length of eyeball given by A - scan USG
K ⇒ Corneal curvature by Kertometer.
