PURPOSE: To compare the clinical visual results and complications of laser-assisted subepithelial keratectomy (LASEK) and epipolis laser in situ keratomileusis (Epi-LASIK). METHODS: A retrospective analysis of a case series of eyes treated with LASEK or Epi-LASIK with a follow-up of six months was performed. Twenty-two eyes were treated with LASEK, and 20 eyes were treated using Epi-LASIK. The main outcome measures were uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), and manifest refraction at one week, one month, three months, and six months after refractive surgery, and the presence of any complications. RESULTS: There was no significant difference of UCVA and mean postoperative spherical equivalent (SE) between the eyes treated with LASEK or Epi-LASIK at one week, three months, and six months. However at one month there was significant difference of UCVA. Additionally, in a comparison between moderate and serve myopia, there was no significant difference of UCVA and mean postoperative spherical equivalent (SE) between groups treated with LASEK or Epi-LASIK at one week, one month, three months, and six months. Seven eyes treated with LASEK and two eyes treated with Epi-LASIK showed persistent epithelial erosion less than one week. Two eyes treated with LASEK exhibited newly-developed corneal opacity, which persisted-through the last visit. CONCLUSIONS: Epi-LASIK showed clinical visual results and complications comparable to LASEK and showed better epithelial healing.

Metastatic leiomyosarcoma to the thyroid is an extremely rare occurrence, and only 18 cases have been reported. Here, we report a case of a 37-year-old woman who presented with multiple masses on the scalp. Excisional biopsy was done and the mass revealed fascicles of smooth muscle fibers which showed positive staining for smooth muscle actin, thus confirming the diagnosis of leiomyosarcoma. The patient was also found to have a 0.9 cm mass within the left thyroid. Fine-needle aspiration was done and the cytological smear showed hypercellular spindle cell clusters with hyperchromatic and large nuclei. Normal thyroid follicular cells were found within or around tumor cells. In this report, we present the cytologic findings of metastatic leiomyosarcoma to the thyroid and offer differential diagnoses of the aspirated spindle cells.
