Comparison of visual effects of FS-LASIK for myopia centered on the coaxially sighted corneal light reflex or the line of sight.

Aim: To compare visual quality after femtosecond laser keratomileusis (FS-LASIK), between the coaxially sighted corneal light reflex (CSCLR) group and conventional ablation line of sight (LOS) group.

Methods: In total, 243 eyes (122 patients) were treated with centration on the CSCLR (visual axis) and 238 eyes (119 patients) treated with centration on the pupil center (LOS). Postoperative outcomes [uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA)], safety index, efficacy index, refractive outcome, ablation center distance from the visual axis, corneal high-order aberrations, subjective discomfort glare and shadowing incidence rate, and contrast sensitivity at 1, 3, and 6mo were measured and compared.

Comparison of corneal flap thickness using a FS200 femtosecond laser and a moria SBK microkeratome.

Aim: To evaluate differences in flap thickness resulting from use of an Alcon Wavelight FS200 femtosecond laser and a MORIA SBK microkeratome when making a 110-µm-thick corneal flap and to identify the potential factors that affect corneal flap thickness.

Methods: A prospective case study was performed on 120 eyes of 60 patients who were divided into two groups for LASIK, each group consisting of 60 eyes (30 patients). The corneal flaps were created using an Alcon Wavelight FS200 femtosecond laser or a MORIA SBK microkeratome.

[Comparison of cornea flap made by femtosecond laser and microkeratome in laser in situ keratomileusis].

Objective: To determine flap thickness variation in 110 µm thickness flap made by FS200 femtosecond laser and sub-Bowman keratomileusis (SBK) microkeratome for studying the potential factors that affect the flap thickness.

Methods: It was a case-control study. Sixty patients were divided into two groups for laser in situ keratomileusis.

[Three kinds of phakic intraocular lens for correction of high myopia].

Objective: To evaluate the efficacy, safety and stability of three kinds of phakic intraocular lens implantation for the correction of high myopia.

Methods: This study included 208 eyes of 110 patients with a mean age of 31 years (21 - 53) from December 2003 to December 2009. Angle-supported lens (Phakic 6H, OII) were inserted into 113 eyes, iris-fixated lens (Artisan, OPHTEC) were inserted into 53 eyes and implantable contact lens (ICL) (V4, STAAR) were inserted into 41eyes.

[Anterior chamber phakic intraocular lens implantation in highly myopic eyes].

Objective: To investigate the stability, predictability and safety of angle-supported phakic intraocular lens (IOL) implantation in high myopia.

Methods: Seventy-six myopic eyes of 40 patients treated with anterior chamber angle-supported phakic IOL (Phakic6H) implantation were followed. The average myopia diopter was (-15.
