Refractive errors are a fairly common eye condition worldwide, and the ophthalmologist should be capable of offering the patient both nonsurgical and surgical solutions to their refractive conditions. Nevertheless, currently, refractive surgery training during residency is poor at best. This paper explores recent evidence to suggest that postsurgical results of patients operated on by residents...

METHODS: is study comprised patients with keratoconus and cataract who had ICRS implantation , followed 6 months later by IOL implantation with corneal relaxing incisions. e uncorrected (UDVA) and corrected (CDVA) distance visual acuities and residual refractive errors, analyzed using vector analysis, were recorded preoperatively, 6 months after ICRS implantation, and 6 months after IOL implant...

Ocular growth is essential to the understanding of the development of refractive errors (RE). ÔThe eye is approximately 17 mm long at birth. From birth to age 6, the eye will grow by around 5 mm, will lose 4 dioptres of corneal power and 20 dioptres of lens power. In the general population, there is a preponderance of emmetropes and the prevalence of ‘acquired’ myopia is only 2% by the age of 6...

PURPOSE To assess the accuracy of intraocular lens (IOL) power predictions for cataract surgery in eyes with primary angle-closure glaucoma (ACG). Because of shifting of the capsular bag apparatus and shortening of the axial length, preoperative calculation of IOL power may be inaccurate for eyes with ACG. MATERIALS AND METHODS This retrospective comparative case series comprised of 42 eyes f...

BACKGROUND Different enhancement procedures have been suggested for reduction of residual refractive errors after SMILE. The aim of this study is to evaluate an improved cap-preserving technique for enhancement after SMILE (Re-SMILE). METHODS A retrospective case series was conducted at Eye subspecialty center, Cairo, Egypt on 9 eyes with myopia or myopic astigmatism (spherical equivalent - 8...

The field of aberrations of the human eye is moving rapidly, being driven by the desire to monitor and optimise vision following refractive surgery. It is important for ophthalmologists and optometrists to have an understanding of the magnitude of various aberrations and how these are likely to be affected by refractive surgery and other corrections. In this paper, I consider methods used to me...

BACKGROUND/PURPOSE To evaluate the relationship between refractive error and vision-related quality of life in 16-year-old students in Taiwan. METHODS A cross-sectional study was designed for 16-year junior-high-school students in Taiwan. Myopia was defined as a spherical refractive error (SRE) < -0.50 D, hyperopia as SRE > +1.0 D, and emmetropia as SRE -0.5-+1.0 D in the better eye. Vision-r...

In modern cataract surgery, spectacle freedom is becoming more and more important. Emmetropia can be achieved for patients with myopic or hyperopic refractive errors by selecting the appropriate spherical lens power. However, approximately 20% of patients who undergo cataract surgery have 1.25 diopters (D) of corneal astigmatism or more. (FerrerBlasco, Montes-Mico et al. 2009; Hoffmann and Hutz...
