Abstract］ Objective To describe the shape of the planar space of the corneal anterior surface of children with emmetropia by using a conic section, and then to plot the changes in asphericity on 36 meridians to deduce the formulae of the three-dimensional shape of the corneal anterior surface.

Paired Samples T test revealed that both the LT and VL decreased (P.01), the AD increased (P.01) after cycloplegia regardless of their refractive state. The AL increased for hyperopic eyes (P.05) and decreased for myopic eyes (P.01) after cycloplegia. For hyperopic eyes, the major keratometer K1 increased (P.05) while for myopic eyes, the major keratometer K1(P.05) and minor keratometer K2 (P.01) decreased after cycloplegia. The mean corneal power of zones 5 mm (MD5) and 7 mm (MD7) decreased with myopic eyes decreased dramatically (P.01). The mean refractive power of the lower half vertical meridian is greater than that of upper half; and the mean refractive power of the lateral half of the horizontal is greater than that of the medial half.

The visual acuity, dioptometry and corneal topography were investigated in a 12-month follow-up study.results the postoperative visual acuity of the 56 eyes(84.8%)was equal to or above the best corrected visual acuity before lasik.conclusion lasik for ametropia after cataract extraction and intraocular lens implantation is an effective and safe surgery.but the indication must be selected appropriately.
