Ophthalmologists have been seeking to achieve the same quality and surgical success for high ametropia as has already been achieved for moderate ametropias. The analysis of refractive outcomes of procedures such as the Ferrara Ring implantation to correct early keratoconus, thermoke...
Irregular astigmatism can result from an eye injury that has caused scarring on the cornea, from certain types of eye surgery or from keratoconus, a disease that causes a gradual thinning of the cornea. Astigmatism tests Astigmatism is detected during a routine eye exam with the same instruments...
scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused bykeratoconusand other corneal irregularities.
premium IOLs like presbyopia-correcting lenses and EDOF lenses are the patients we should all absolutely be striving to correct to zero astigmatism—or as close as possible, considering the limitations that exist,” he stresses. “Obviously, those patients...
Phakic IOLs: Coming to an Eye Near You Q: Who's a candidate for the forthcoming phakic IOLs? A: In general, a candidate for a phakic IOL is anyone who isn't a good candidate for corneal refractive surgery. This includes patients with high myopia, thin corneas, keratoconus or ... PC...
With Maria's diagnosis established, Dr. Chiu learned that Maria had only been prescribed glasses to correct her vision. "This surprised me because for many keratoconus patients, glasses don't work adequately once the condition becomes more advanced and the eye shape has become distorted," said ...

Deep Phenotyping is shedding new light on congenital corneal opacities, and with the initial diagnoses, physicians should also delve deeper to avoid overlooking the causes of some ocular anomalies. Deep phenotyping is key to correct diagnosis with corneal opacities and can ensure physicians do not...
The ability to confirm the presence of keratoconus (KC), keratoglobus (KGB) or pellucid marginal degeneration (PMD) is only half of the battle. Knowing how to best correct the induced irregular astigmatism and ametropia is equally important for patient retenti...
Custom contacts.Custom-made contact lenses are available in both gas permeable and soft lens materials. Commonly prescribed custom GP lenses are designed to correct vision problems caused bykeratoconusand other hard-to-fit-eyes.Custom contact lensesare significantly more costly than conventional GP or ...
