ABSTRACT

The purpose of this study was to evaluate the predictability, efficacy, and safety of LASIK in the management of both undercorrection and overcorrection following RK. This prospective study included 30 eyes of 18 patients. All patients underwent previous RK surgery to treat myopia and all of them had residual refractive defect after surgery. Patients were divided according to this residual refractive defect into two groups: Group 1 [undercorrection group] included 17 eyes and group 2 [overcorrection group] included 13 eyes. All eyes underwent LASIK to correct the residual defect. The mean interval between RK and LASIK was 26 +/- 9.1 months [range 12-60 months]. All the patients were followed up for at least six months postoperatively. At the end of the 6-month follow-up period, in group 1, 14 eyes [82%] were within the +/- ID zone of intended correction, 13 eyes [76%] had UCVA of more than 0.5, and 16 eyes [94%] showed improvement or no change in BCVA. In group 2, 10 eyes [77%] were within the +/- ID zone of intended correction, 9 eyes [69%] had UCVA of more than 0.5 and 12 eyes [93%] showed improvement or no change in BCVA. Laser in situ keratomileusis performed to treat undercorrection and overcorrection after RK was predictable, effective and safe. However, special precautions should be taken pre- and intraoperatively to ensure its safety

ABSTRACT

Several techniques are used to reposit dislocated intraocular lenses [IOLs]. In cases of a dislocated capsular bag containing the IOL, a dislocated IOL with a large haptic, or a miotic pupil, it is not easy to see the haptic ends to place the suture loop. A scleral fixation technique that creates 2 corneal tunnels was used. A double armed 10-0 polypropylene suture loop can be introduced through 1 corneal tunnel and placed around any accessible part of the haptic with the help of a bent 26 gauge needle. This step can be repeated through the second corneal tunnel to catch the other haptic, if it is displaced
