The Effects of Cataract Surgery on Children's Vision: A Systematic Review.

Background: Five-fifths of all incidents of blindness in Saudi Arabia may be attributed to cataracts. Cataracts are the second major cause of blindness, responsible for 35.5% of cases.

Satisfaction Rate After Laser Correction of Presbyopia (Presbyond) Among Patients Aged 40 Years and Older in Taif, Saudi Arabia.

Background Presbyopia is a physiological condition arising due to the loss of accommodation within the crystalline lens. One of the most widely accepted theories of the mechanism of accommodation was that in response to ciliary muscle contraction, the crystalline lens thickness increases, the lens diameter decreases, and both the anterior and posterior curvature of the lens increase, resulting in an increase in lenticular power therefore, accommodation. A contrasting theory suggests that ciliary muscle contraction leads to a selective increase in equatorial zonular tension, with the lens equator moving toward the sclera and the equatorial diameter of the lens increasing.

Smartphone Use and its Impact on Ocular Health among University Students in Saudi Arabia.

Background: People are increasingly using mobile phones rather than fixed telephones. Nearly everyone has a mobile phone and the vast majority of these are smartphone. The patterns of smartphone activities may put a significant number of populations especially students at risk of negative ocular problems.

Prevalence of keratoconus among patients seeking laser vision correction in Taif area of Saudi Arabia.

Purpose: To determine the prevalence of keratoconus among patients seeking laser vision correction (LVC).

Methods: Retrospective study of 1374 eyes of 687 patients (335 males, 352 females) who underwent keratoconus screening as a part of routine preoperative evaluation prior to LVC at the Tadawi surgical centre, Taif, Saudi Arabia from January 2014 to June 2015. The diagnosis of keratoconus was based on evaluation of Pentacam derived parameters.

Relative Proportion Of Different Types Of Refractive Errors In Subjects Seeking Laser Vision Correction.

Background: Refractive errors are a form of optical defect affecting more than 2.3 billion people worldwide. As refractive errors are a major contributor of mild to moderate vision impairment, assessment of their relative proportion would be helpful in the strategic planning of health programs.

Comparison of microkeratome assisted sub-Bowman keratomileusis with photorefractive keratectomy.

Purpose: To compare the outcomes of photorefractive keratectomy (PRK) and thin-flap Laser-Assisted in Situ Keratomileusis/sub-Bowman keratomileusis (SBK) with intended flap thicknesses of 100 μm using the One Use-Plus SBK microkeratome.

Methods: Ninety-eight eyes of 52 subjects with myopic manifest refraction spherical equivalent (MRSE) of up to -5 diopters (D), a stable refraction for 1 year and a corrected distance visual acuity (CDVA) of at least 20/20 in each eye which had undergone SBK or PRK were reviewed retrospectively. Primary outcome measures were MRSE, uncorrected distance visual acuity (UDVA), CDVA, pachymetry and higher order aberrations (HOA).

Viscoelastic substance in prefilled syringe as an etiology of Toxic Anterior Segment Syndrome.

Context: Toxic Anterior Segment Syndrome (TASS) is an acute postoperative inflammatory reaction in which a noninfectious substance enters the anterior segment and induces toxic damage to the intraocular tissues.

Objective: To present etiologic investigation of two consecutive clusters of TASS. TASS outbreak and investigation: This paper presents two consecutive clusters of TASS in 15 of the 24 uneventful surgeries and the investigation carried out to find the etiology.

Reproducibility of flap thickness in sub-Bowman keratomileusis using a mechanical microkeratome.

Purpose: To examine the predictability of flap thickness using a mechanical microkeratome (One Use-Plus) and identify factors related to variations in flap thickness in sub-Bowman keratomileusis (SBK).

Setting: Tadawi Surgical Center, Taif, Saudi Arabia.

Design: Retrospective case series.

Posterior chamber toric phakic IOL implantation for the management of pediatric anisometropic amblyopia.

Purpose: To report the outcomes of toric posterior chamber phakic intraocular lens (PIOL) implantation in children for the treatment of amblyopia due to anisometropia with astigmatism.

Methods: Six eyes of 6 amblyopic patients aged 5 to 15 years underwent toric PIOL (Visian Toric ICL; STAAR Surgical Company, Monrovia, CA) implantation for refractory anisometropic amblyopia. Preoperative and postoperative clinical evaluation included slit-lamp microscopy, visual acuity, anterior/posterior segment examination, and cycloplegic refraction.
