This study retrospectively analyzed data from the German Keratoplasty Registry to delineate trends in corneal transplantation.

Study design

The authors distributed questionnaires to 111 ophthalmologic departments in Germany to ascertain the number of corneal transplants performed between 2001 and 2016, as well as the indications for each procedure.

Outcomes

Analysis of responses from 94 of the 111 departments revealed that keratoplasties increased by 1.5-fold over the study period, from 4,730 in 2001 to 7,325 in 2016. By 2014, lamellar keratoplasties were performed more often than penetrating keratoplasties. In 2016, German surgeons performed 12 times more Descemet's membrane endothelial keratoplasties (DMEKs) than Descemet's stripping endothelial keratoplasties (DSEKs). Throughout the study period, Fuchs endothelial corneal dystrophy remained the most common indication for surgery. The proportion of deep anterior lamellar keratoplasties (DALKs) never exceeded 6% (269 in 2011). Keratoconus was a far less common indication for surgery in Germany than in other European countries.

Limitations

A significant portion (15%) of the departments did not complete the questionnaire. The study’s retrospective nature precluded analysis of visual or anatomical outcomes.

Clinical significance

This study reveals a dramatic shift to lamellar keratoplasty over the last decade across the world. These findings also highlight the increased prominence of DMEK, which is widely considered to be in its early developmental stages in the US but is commonly performed in nations such as Germany.

I Spy a Stye in Your Eye

Written by Dr. David Evans Last modified on August 6, 2018 What’s that small, red, pimple-like bump on your eyelid that’s causing so much discomfort? It’s probably a stye (sometimes referred to as a sty or hordeolum). Besides being difficult to say 5 times quickly, an eye stye is a type of localized infection that can occur along the base of your eyelashes or underneath your eyelid. Styes that form along the base of the eyelashes are called external styes. They typically occur as a result of an infected eyelash hair follicle and look like the type of pimple that occurs when your pores are clogged with dirt and oil. Styes that form inside the eyelid are called internal styes. Similar to external styes, they are caused by an infection of an oil-producing gland behind the eyelid rather than an eyelash hair follicle. Internal styes result in generalized swelling of the eyelid rather than forming a pimple-like bump. Stye Symptoms As a stye develops, you might begin to experience pain

Post-LASIK Refraction and Pregnancy – Much Ado About Nothing?

Image
Written by Dr. David Evans Last modified on August 23, 2018 During pregnancy, women experience a drastic shift in their hormonal balance that has a ripple effect throughout the body. The spike in hormones like progesterone, estrogen, prolactin, oxytocin and relaxin are all important for a healthy pregnancy, but these increased levels can also impact gastrointestinal processes, blood pressure, skin pigmentation and, you guessed it, ocular health. Due to refractive changes that often occur during pregnancy, most refractive surgeons advise against LASIK during pregnancy, instead suggesting women wait several months after giving birth before considering treatment. Women who have already undergone LASIK may then wonder if the changes in ocular health that can occur during and after pregnancy impact post-LASIK refraction. New research presented by John Kanellopoulos, MD, New York University Medical School, NY, and LaserVision.gr seems to throw cold water on any such concern. The Eyes an
