Refraction in eye not affected by:: (A) Removal of vitreous, (B) Lens thickened, (C) Anterior chamber depth increased, (D) Axial length changed
Answer is C. Ans. c. Anterior chamber depth increasedREFRACTORY POWER DEPENDS ONRadii of curvatureDifference in refractive index between two media at interface of refraction. (Anterior surface of cornea has maximum refractive power due to maximum change (0.376) in refractive index from air to cornea.Axial length of eyeball
