cataract and refractive ophthalmology

Andrzej Grzybowski, Weronika Wasinska-Borowiec, Charles Claoué
Immediately sequential bilateral cataract surgery (ISBCS) is currently a "hot topic" in ophthalmology. There are well-documented advantages in terms of quicker visual rehabilitation and reduced costs. The risk of bilateral simultaneous endophthalmitis and bilateral blindness is now recognized to be minuscule with the advent of intracameral antibiotics and modern management of endophthalmitis. Refractive surprises are rare for normal eyes and with the use of optical biometry. Where a general anesthetic is indicated for cataract surgery, the risk of death from a second anesthetic is much higher than the risk of blindness...

BACKGROUND: Cataract surgery is the most common surgical procedure in ophthalmology. Biometry data and accurate intraocular lens (IOL) calculations are very important in achieving the desired refractive outcomes. The aim of this study was to compare measurements using a new optical low coherence reflectometry (OLCR) biometer (OA-2000) and the gold standard partial coherence interferometry (PCI) optical biometer (IOLMaster 500). METHODS: Ocular biometry of cataract patients were measured by the OA-2000 and IOLMaster 500 to compare keratometry (K), axial length (AL), anterior chamber depth (ACD), white-to-white (WTW) diameter, and IOL power using the SRK/T formula...

BACKGROUND: Some pseudophakic patients implanted with a monofocal intraocular lens (IOL) have good near visual acuity (VA) with their distance correction. The objective was to evaluate the prevalence of pseudo-accommodation in children after bilateral cataract surgery, without amblyopia, and to define its mechanisms. METHODS: Observational study that took place in a pediatric ophthalmology department, Paris, France. A total of 68 eyes were included, 40 from 23 children and 28 from 14 adults, with a corrected distance VA above 20/25 and a normal near VA (20/25) with +3 addition...

PURPOSE: To evaluate postoperative outcomes and visual performance in intermediate distance after implantation of a +1.5 diopters (D) addition, aspheric, rotational asymmetric multifocal intraocular lens (MIOL). METHODS: Patients underwent bilateral cataract surgery with implantation of an aspheric, asymmetric MIOL with +1.5 D near addition. A complete ophthalmological examination was performed preoperatively and 3 months postoperatively. The main outcome measures were monocular and binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), distance corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity (UNVA) and distance corrected keratometry, and manifest refraction...

PURPOSE OF REVIEW: Intraoperative floppy iris syndrome (IFIS) occurs in 2% of cataract surgeries and is associated with an increased risk of surgical complications. These complications can be avoided when high-risk patients are identified by preoperative screening and appropriate measures are used intraoperatively. The purpose of this article is to review emerging risk factors for IFIS and to summarize management strategies used in IFIS. RECENT FINDINGS: Although α1-antagonists in general, and tamsulosin (Flomax, Jalyn) in particular, have long been associated with IFIS, recent studies have more firmly demonstrated the elevated risk of IFIS attributed to tamsulosin...

We describe the ocular features of the chromosome 22q11.2 duplication syndrome and provide ophthalmologic examination recommendations for affected patients. The medical records of 19 children with chromosome 22q11.2 duplication who had undergone complete ophthalmological examination, including dilated fundus examination and cycloplegic refraction, were studied retrospectively. Over half of the children with 22q11.2 duplication syndrome were found to have visually significant ocular abnormalities, including 6 with strabismus, 2 with moderately high astigmatism requiring glasses, 1 with unilateral congenital cataract requiring surgery, 1 with optic disk drusen, 1 with bilateral megalocornea with normal eye pressures, 1 with nystagmus that resolved spontaneously, and 1 with delayed visual maturation...

The 2001 NHG practice guideline on 'Refraction disorders' was revised for the second time in October 2015. The title has been changed to 'Visual symptoms', since besides refraction disorders other conditions such as glaucoma, macular degeneration, cataract and acute eye symptoms are also covered. The ophthalmologist is the specialist to whom GPs refer patients most often. Apart from the GP, ophthalmologist and youth health care physician, various other allied health professions are involved in eye healthcare...

Amblyopia is a frequent vision disorder with a prevalence of 3-6%, for which early treatment is more effective. More than half of the cases of amblyopia are due to refractive errors so that they are not obvious due to strabismus or other ocular abnormalities; therefore, examinations for early recognition are essential. Because no nationwide ophthalmological examination of infants with cycloplegia has been established in Germany, screening for refractive errors in the first 3 years of life could be very helpful...

Ophthalmology residents must become competent in the use of a variety of intraocular lenses (IOLs) and refractive technologies designed to reduce spectacle use after cataract surgery. Our study of visual acuity outcomes with toric IOLs at the Harry S. Truman Memorial Veterans' Hospital revealed that residents achieved an uncorrected visual acuity of 20/40 or better in 88% of the surgeries they performed, a rate comparable to that reported by other residency programs and by cataract surgeons.

The prevalence of blindness increases rapidly with increasing age. Globally, there are some 32 million people who are blind and 191 million with poor vision. The leading cause of blindness worldwide is cataract, whereas uncorrected refractive error causes most poor vision. The rates of blindness from diabetes and macular degeneration are rapidly increasing, and age-related macular degeneration is the leading cause of blindness in developed countries. Three quarters of this blindness can be prevented or treated, and although the absolute number of blind people increased slightly between 1990 and 2010, very importantly, the prevalence of blindness has been halved as eye care programs and particularly cataract services have developed...
