Abstract:
Management of mis-dissected lenticule during Small-incision lenticule extraction (SMILE) is technically challenging and might be experienced more by novice surgeons especially in eyes with low refractive errors and thin lenticules. Presently, we describe a rescue method of inverse centripetal dissection (ICD) to manage mis-dissected lenticules. In this technique, after inadvertent dissection of posterior plane prior to anterior plane, the double-ended SMILE dissector is rotated along its shaft axis clockwise from the left upper margin of the mis-dissected lenticule to form an inversely folded lenticule which is then subsequently dissected centripetally till midline. This is then extracted by performing lenticulorrhexis with a pair of microforceps. We performed this technique in 10 eyes of 10 patients and the lenticule extraction was accomplished successfully in all eyes. At six months follow-up, the uncorrected visual acuity was 20/20 with a clear interface in all eyes. The ICD approach might serve as a useful rescue technique for managing mis-dissected lenticules.
