Simple method of measuring ocular rotation in supine position during small incision lenticule extraction.

Aim: To introduce a novel measurement method of static cyclotorsion in small incision lenticule extraction (SMILE) and to investigate the effect of preoperative parameters on cyclotorsion and the effect of cyclotorsion on postoperative outcomes.

Methods: The medical records of 242 patients and 484 eyes who underwent SMILE surgery were retrospectively reviewed. Preoperative intraocular pressure, refractive error, and corneal thickness were investigated.

The Association between the Frequency of Rhegmatogenous Retinal Detachment and Atmospheric Temperature.

Rhegmatogenous retinal detachment (RRD) frequency was observed to be higher with an increase in the daily temperature range. This showed that a wide daily range of temperature, rather than the absolute value of the temperature, is associated with the occurrence of RRD. .

Visual outcomes after three different surgical procedures for correction of refractive error in patients with thin corneas.

Aim: To investigate and compare the visual and refractive outcomes of small incision lenticule extraction (SMILE), laser assisted sub-epithelial keratomileusis (LASEK), and LASEK combined with corneal collagen cross-linking (LASEK-CXL) surgery in patients with less than 500 µm of central corneal thickness (CCT).

Methods: The retrospective medical records review was conducted on the patients with CCT less than 500 µm treated with SMILE, LASEK, and LASEK-CXL. There was a total of 172 eyes, 76 eyes were in the SMILE group, 53 eyes in the LASEK group, and 43 eyes in the LASEK-CXL group.

Rainbow halos occur less following implantation of extended range of vision one-piece intraocular lenses diffractive bifocal intraocular lenses.

Aim: To evaluate clinical outcomes following implantation of an extended range of vision intraocular lens (IOL), the ZXR00, and a diffractive multifocal IOL with +2.75 diopters (D) add power, the ZKB00.

Methods: Totally 30 patients who underwent either bilateral implantation of the ZXR00 IOL with intended emmetropia (ZXR00 emmetropia group: 20 eyes) and intended micromonovision (ZXR00 monovision group: 20 eyes), or bilateral implantation of the ZKB00 IOL with intended emmetropia (ZKB00 group: 20 eyes) were included in this study.

Near reading speed changes after panretinal photocoagulation in diabetic retinopathy patients: a prospective study using an iPad application for the measurement of reading speed.

Purpose: To investigate the changes in the near reading speed after panretinal photocoagulation (PRP) in diabetic retinopathy patients.

Methods: This non-randomized, prospective, clinical study enrolled diabetic retinopathy patients who underwent PRP from January 2016 to June 2017. The near reading speed was measured before and 1 week, 1 month, and 4 months after PRP by using an iPad application for the assessment of reading speed; near best-corrected visual acuity (BCVA) and subfoveal choroidal thickness (SFCT) were also analyzed.
