[Two millimeter micro incision lenticule extraction surgery with minimal invasion: a preliminary clinical report].

Objective: To report the clinical results of micro incision lenticule extraction (MILE) to correct myopia or myopia with astigmatism, and enlighten its viability and mechanism.

Methods: Prospective case-control study. All patients enrolled were treated by the VisuMax femtosecond laser system to correct refractive errors.

[Early outcomes of corneal sensitivity changes after small incision lenticule extraction and femtosecond lenticule extraction].

Objective: To evaluate and compare the recovery of central and peripheral corneal sensitivity in the early period after small incision lenticule extraction (SMILE) and femtosecond lenticule extraction (FLEx).

Methods: In this study, 47 cases (87 eyes) which underwent SMILE and FLEx were included. Central, superior, inferior, nasal and temporal corneal sensitivity was measured using a Cochet-Bonnet esthesiometer (Luneau Ophthalmologic) before and 1 week, 1 month, and 3 months after SMILE and FLEx.

[Clinical study of femtosecond laser corneal small incision lenticule extraction for correction of myopia and myopic astigmatism].

Objective: To evaluate the safety, efficacy, predictability, stability and complications of femtosecond laser corneal small incision lenticule extraction (SMILE) procedure for the correction of myopia and myopic astigmatism.

Methods: In this prospective study, 50 patients (88 eyes) with myopia and myopic astigmatism were chosen to be performed SMILE procedure randomly. These patients were followed up at 1 day, 1 week, 1 month and 3 months postoperatively and were examined for uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, intraocular pressure (IOP) and corneal topography.

Ocular higher-order aberration features 10 years after photorefractive keratectomy.

The aim of the present study is to re-evaluate the original cohort of patients who participated in the first photorefractive keratectomy (PRK) trial in the 1990s, especially their optical performance. Forty-four eyes (24 patients) of the original cohort who underwent PRK using the NIDK EC-5000 excimer laser platform returned 10 years (range 9-14 years) postoperatively to have higher-order aberrations (HOAs) recorded. Wavefront aberrations were measured using Wavescan (VISX, Santa Clara, CA, USA) and calculated for 3- and 6-mm pupil size.

[Research on the visual performance and effects of higher order aberration after Epi-LASIK for myopia].

Objective: To investigate changes of visual performance and effects of higher order aberration on visual performance after Epi-LASIK for myopia.

Method: In this prospective study, 102 patients were included. The trial group had 52 patients with Epi-LASIK, and 50 cases with LASIK as the control group.

[The expression of TGF-beta1 and bFGF after LASEK and the effects of 20% ethanol exposure on corneal wound healing].

Objective: To assess the effects of 20% ethanol used in LASEK on corneal wound healing.

Methods: Forty-eight eyes from 24 rabbits were deepithelialized by two techniques. The epithelium were detached with either 20% ethanol (applied for 30 seconds) or mechanical scraping, then ablated was performed.
