| If the lens had an index of 1.53, the dioptric value of that radius of curvature would be 4.64 diopters. |
| Along with relieving the eyes and headache, it gradually decreased diopters. |
| This was reduced at 12 months postoperatively to 1.75 prism diopters in the myectomies and to 3 prism diopters in the recessions. |
| Corrective lenses compensate for the excessive positive diopters of the myopic eye. |
| The degree of astigmatism should not exceed more than four diopters. |
| Increased negative keratometric diopters and oblate asphericity of the PCC are common after LASIK leading to mild keratectasia. |
