Effect of preoperative tear function on early functional visual acuity after laser in situ keratomileusis.

Purpose: To assess the effect of preoperative tear function on early changes in functional visual acuity (FVA) after laser in situ keratomileusis (LASIK).

Setting: Minamiaoyama Eye Clinic, Tokyo, Japan.

Methods: This prospective single-center study assessed the effect of preoperative and postoperative tear functions on FVA in 30 eyes of 15 patients who had LASIK.

Dry eye after laser in situ keratomileusis.

Purpose: To determine whether patients undergoing laser in situ keratomileusis have postoperative dry eye.

Methods: In this retrospective, interventional case series, 124 eyes of 64 consecutive patients who underwent laser in situ keratomileusis were examined for a dry eye symptom, Schirmer test with anesthesia, tear clearance rate, tear break-up time, vital staining for ocular surface, corneal sensitivity, and blink rate. All values were compared before and after surgery (1 month, 3 months, 6 months, and 1 year) and values of P <.

Transplanted corneal stromal cells in vitreous reproduce extracellular matrix of healing corneal stroma.

Purpose: To characterize the extracellular matrix (ECM) formed by corneal stromal cells after injection into the vitreous. This will provide a basis for future studies on the function of corneal ECM macromolecules.

Methods: Cell line from rabbit dermal fibroblasts (RAB9) and primary cultures of rabbit corneal stroma fibroblasts (NRCF) were grown to confluence.
