Refractive power of eye depends upon mainly following factor/factors –a) Lensb) Corneac) Vitreous haemorrhage d) Aqueous Humoure) Axial length of the eye
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
