Small Incision Lenticule Extraction in Myopic Eyes With Corectopia After Intraocular Lens Implantation

We present a case of ametropia corrected by small incision lenticule extraction (SMILE) in a corectopia eye after cataract surgery. The patient's optical zone, nomogram, and centration were carefully considered. The intended corrections were -6.60 - 1.25 x 175 OD and -6.85 - 0.50 x 10 OS. M-sized and S-sized cones were recorded in the right and left eye, respectively. The diameter of the right eye optical zone was 7.00 mm, whereas that of the left eye was 6.50 mm. The corneal vertex was determined using the film mark method as the scanning center. Three months after surgery, the uncorrected distance visual acuities were 20/20 OD and 20/13 OS. The effective optical zone was 6.5 and 5.5 mm in the right and left eyes, respectively. It is feasible to correct ametropia with SMILE in patients with corectopia after intraocular lens implantation. The large optical zone will compensate for the visual disturbance.
