Purpose: To evaluate the postoperative refraction of intended undercorrection after intraocular lens (IOL) implantation in pediatric cataract patients. Design: A cross-sectional study (data collected by retrospective chart review). Patients and methods: The medical records of children aged under 10 years, who underwent cataract surgery with IOL implantation at the Ramathibodi Hospital between January 2000 and May 2018, were reviewed. IOL power calculations were 30%, 25%, 20%, 15% and 10% under-corrected if children were aged 6-12, 13-24, 25-36, 37-48 and 49-60 months, respectively...

PURPOSE: To identify the preoperative biometric factors, including subfoveal choroidal thickness (CT), associated with refractive outcome after cataract surgery in eyes with primary angle closure (PAC). METHODS: This study included 50 eyes of 50 PAC patients who underwent uneventful cataract surgery. Preoperatively, anterior segment parameters including anterior chamber depth (ACD) and lens vault were determined by anterior segment optical coherence tomography. Subfoveal CT was measured by spectral domain optical coherence tomography enhanced depth imaging before and at one month after surgery...

PURPOSE: The technological improvements in optical biometers have made cataract surgery evolve to the level of refractive surgery. This study assessed the correlation and agreement between a biometer using swept-source optical coherence tomography technology (IOLMaster 700; Carl Zeiss Meditec, Jena, Germany) and a biometer using optical low-coherence reflectometry (Lenstar; Haag Streit, Koeniz, Switzerland). PROCEDURES: Optical biometric measurements were taken with the IOLMaster 700 and the Lenstar on 129 eyes of 129 patients referred for cataract surgery...

PURPOSE: The aim of this study is to evaluate the effectiveness and predictability of photorefractive keratectomy (PRK) for correcting residual refractive error following cataract surgery with premium intraocular lens (IOL) implantation. METHODS: We conducted a retrospective review of the medical records of patients who received PRK for correcting residual hyperopia, myopia, and/or astigmatism due to unsatisfied uncorrected distance visual acuity (UDVA) after cataract extraction with implantation of aspheric, diffractive multifocal, or toric IOL from September 2011 to December 2017...

PURPOSE: To evaluate the refractive predictability obtained with an extended range of vision intraocular lens in eyes with previous myopic laser in situ keratomileusis, confirming which intraocular lens power formula provides the most accurate calculation. METHODS: The study enrolled 71 eyes with previous successful myopic laser in situ keratomileusis surgery of 43 patients undergoing cataract surgery with implantation of the extended range of vision intraocular lens TECNIS Symfony (Johnson and Johnson Vision)...

Objective: This study examined the prevalence of keratoconus among patients who were interested in undergoing refractive surgery. Corneal tomography measurements were used to help detect keratoconus. Methods: Adult subjects who presented to the private hospital Cataract and Refractive Surgery Unit (Abha, Saudi Arabia) for refractive surgery evaluation were considered for inclusion in this cross-sectional, retrospective study. All subjects were from the Aseer province, a southern, high-altitude region in Saudi Arabia, and presented between January and December 2017...

PURPOSE: To audit and analyse the accuracy of current biometric formulae on refractive outcomes following cataract surgery in patients with axial length less than 22 mm. METHODS: A total of 84 eyes from 84 patients with axial length <22 mm were identified from consecutive patients undergoing cataract surgery retrospectively at a single university hospital. All subjects had biometry using the IOLMaster (Carl Zeiss Meditec, Inc, Dublin, CA, USA) and a Sensar AR40 intraocular lens implant (Abbott Medical Optics, CA, USA)...

To investigate the intraocular pressure (IOP) changes after cataract surgery, and its relationship with refractive conditions.IOP after phacoemulsification with intraocular lens (IOL) implantation was retrospectively reviewed. Patients were classified into 3 groups by refractive conditions: emmetropia, mild to moderate myopia, and high myopia. Basic information was collected including age, sex, place of IOL, and operating surgeon, with IOP and refractive conditions measured before surgery, and 1, 7, 30, and 90 days after surgery...

To review binocular and accommodative disorders documented after corneal or intraocular refractive surgery, in normal healthy prepresbyopic patients. A bibliographic revision was performed; it included works published before 1st July 2017 where accommodation and/or binocularity was assessed following any type of refractive surgical procedure. The search in Pubmed yielded 1273 papers, 95 of which fulfilled the inclusion criteria. Few publications reporting binocular vision and/or accommodative changes after refractive surgery in normal subjects were found...
