November consultation #4

Late IOL dislocation is becoming a more frequently occurring event after previously uncomplicated cataract surgery. Pseudoexfoliation, status post-vitrectomy, myopia, trauma, and uveitis are the most common causes, and these are at cumulative risk.

Publication date: Available online 15 January 2020Source: Journal of American Association for Pediatric Ophthalmology and StrabismusAuthor(s): Arif O. Khan, James BaconA 56-year-old woman with pseudophakia and glaucoma was referred because of left eye hypotropia and esotropia noted following superotemporal Ahmed glaucoma valve implantation in that eye. Examination suggested left heavy eye syndrome, and it was confirmed the patient had high axial myopia before her cataract surgeries. Both nasal displacement of the left superior rectus muscle and inferior displacement of the left lateral rectus muscle were noted intraoperati...

In most cases, myopia occurs due to excessive axial elongation of the eyeball. Nowadays, it is possible to correct vision even in cases of high myopia using various types of spectacles, contact lenses (CL) or refractive surgery. However, a significant concern related to myopia is the increased risk of ocular pathologies related to excessive eye growth, such as glaucoma, cataract, idiopathic retinal detachment or choroidal neovascularization [1]. In recent decades, the prevalence of myopia has increased dramatically worldwide [2 –4].

Purpose of review Astigmatism correction in cataract surgery is a common surgical challenge. Although there are numerous approaches to its treatment during cataract surgery, there remains a lack of consensus on what level of postoperative astigmatism to target. We examine the literature to determine the effect of astigmatism on visual function and provide a recommendation on how much to treat in cataract surgery. Recent findings Distance visual acuity decreases as myopic, hyperopic, or mixed astigmatism increases. Near visual acuity decreases with hyperopic astigmatism but improves with myopic astigmatism. The effect ...

Rationale: Spherophakia is a rare diagnosis which is often associated with a shallow anterior chamber, angle-closure glaucoma, lens subluxation, and lenticular myopia. When cataracts occur with subluxation of the lens, vision is often markedly affected. This often presents surgeons with a unique challenge of maintaining good visual outcomes while minimizing potential complications. Patient concerns: A 48-year-old female was referred for ophthalmological assessment due to decreased vision in the left eye. In the left eye, the best-corrected visual acuity at distance was 20/125 with manifest refraction of −6.5D + ...

The actual numbers of people blind or with poor vision continue to increase despite so excellent progress that is being made in reducing the prevalence or percentage of people affected. More attention is required to provide quality outcomes for cataract surgery, prevent and manage myopia, detect and treat diabetic retinopathy, glaucoma, and age-related macular degeneration (AMD). Although more ophthalmologists are needed to provide this eye care, it is important that ophthalmologists work in effective teams with allied eye health personal to be able to meet the community needs.

While welcoming recent successes in eliminating common conditions such as trachoma in eight countries, the World Health Organization (WHO) highlighted evidence indicating ...

It is well known that preoperative abnormal topographic abnormality, low residual stromal bed thickness, thin corneas, young age, and high myopia are factors that might increase the risk for developing corneal ectasia after corneal refractive surgery.1 As outlined, this patient had thicker than average corneal thickness. The anterior elevation map showed an asymmetric bowtie pattern with an I –S index of 1.0 D, which is below the recognized 1.4 D cutoff, and there was no skewed radial axis. Furthermore, the patient was 23 years old and the treatment size was small; therefore, this patient was deemed a suitable candidate for SMILE.

The prevalence of myopia is much higher than hyperopia. Hence, there are relatively few studies investigating phakic intraocular lens (pIOL) implantation for the correction of hyperopia. This review aimed to summarize the available relevant literature on the efficacy and safety of pIOL implantation for the correction of hyperopia and hyperopic astigmatism. At present, two types of pIOLs are used to correct hyperopia and hyperopic astigmatism: anterior chamber iris-fixated pIOLs and posterior chamber implantable collamer lenses.

Conclusion: We found VCD to have the strongest relation with AL. VCD: AL was more consistent and showed a strong relation to ocular biometry across all ALs. This suggests the possible utility of the ratio VCD: AL while evaluating ocular growth, refractive status, and myopia-related complications.
