Corneal thickness is not directly related to corneal strength. This patient had a thick cornea but was obviously weak biomechanically, which can be seen on topography as FFKC pre-op. This patient developed ectasia 27 months after LASIK Source: William B. Trattler, M.D.

Don’t exclude thin cornea patients from LASIK for fear of ectasia

The belief that LASIK shouldn't be performed on thin corneas because of the risk of sight-threatening ectasia isn't scientifically valid, according to one researcher. Abnormal corneal topography is the most important preop risk factor for the complication, said William Trattler, MD.

Double trouble: Diplopia following cataract or refractive surgery

Pre-existing strabismus and a family history of this are two red flags to look for when trying to head off diplopia in cataract patients, according to Kammi B. Gunton, M.D., assistant surgeon, Wills Eye Institute, Philadelphia. Investigators led by Dr. Gunton reported on the incidence and causes of diplopia following cataract and refractive surgery in the September 2010 issue of Current Opinions in Ophthalmology.

The water-drinking test in glaucoma

The water-drinking test was proposed decades ago as a way to diagnose glaucoma. Following a baseline IOP measurement, the subject quickly consumes one liter of water and undergoes subsequent IOP measurements every 15 minutes for 1 hour. A glaucomatous eye with impaired outflow would be less able than a normal eye to adapt to the fluid influx and thus should manifest an IOP rise.

Managing makeup after surgery

The use of makeup is important to many of our patients. I have noticed it to be one of the first questions many patients ask. Knowing the majority of endophthalmitis cases arise from lid bacteria, makeup usage after surgery is not a small consideration. You may be interested to see how some of your colleagues deal with this issue and a few other post-op restrictions.
