Refractive power of eye depends upon mainly following factor/factors –a) Lensb) Corneac) Vitreous haemorrhage d) Aqueous Humoure) Axial length of the eye: (A) abc, (B) bcd, (C) abe, (D) acd
Answer is C. Factors that determine the refractive power of the eye 

Power of the cornea (determined by refractive index & radius of curvature)
The depth of the anterior chamber (the distance of the lens from the cornea)
The diopter power of the lens
The length of the eye
