IOL Master keratometry, Pentacam, Scheimpflug, equivalent keratometry reading
The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

25 years of OCT
David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...Climatic droplet keratopathy

Cataract and Refractive
Contemporary laser in situ keratomileusis (LASIK) is safe and effective. It remains the dominant intervention in routine refractive surgery for a good reason: predictable results, rapid visual recovery, and relatively simple strategies for revision treatment. Over 95% of patients are...

Cataract and Refractive
This multicentre, retrospective, interventional case series assesses the outcomes of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in 113 patients taking isotretinoin between January 2003 and September 2017. Isotretinoin is contraindicated for LASIK and PRK and patients are...
