Managing Microbial Keratitis

Infectious keratitis is a prevalent source of vision loss. While data from the 1990s report incidence as 30,000 cases per year in the United States, a newer study suggests this number has more than doubled. A small but significant percentage of these eyes go on to require corneal transplantation; between 2% and 6% will require an urgent transplant and an even higher percentage will require surgery to ameliorate resultant scars. A smaller number, perhaps as high 1.8% of ulcers seen at academic centers, go on to require enucleation or evisceration.

Because of the potential for severe vision loss, microbial ulcer management requires critical thinking at nearly all junctures, as well as careful and thoughtful follow-up. Based on the severity of infection upon diagnosis, the degree of virulence of the particular microbe and patient-specific features, corneal infections can sometimes progress despite aggressive and appropriate intervention. The good news, however, is that when these infections are identified and treated early, the odds of a favorable outcome are much greater.

Managing Corneal GP Complications

The advent of soft disposable contact lenses permanently altered the contact lens landscape, resulting in the decline of corneal gas permeable (GP) lens fitting. GP lenses are increasingly relegated to patients with complex prescriptions or high vision demands, and specialty designs such as custom soft toric, hybrid and scleral lenses are now widely available and steadily growing in popularity. Consequently, corneal GP lenses are often overlooked as a first choice. 

Thanks to today’s technology, complications related to contact lens overwear and poor lens-to-cornea alignment can be identified early on to help avoid permanent corneal damage. It is important to be aware of common GP lens complications and understand how to troubleshoot in order to maintain good corneal health and lasting comfort.

Let’s Make It Less Complex

Specialty contact lens designs help us restore significant visual function in patients with difficult prescriptions and corneal conditions. As these designs have flourished, so too have available options for these individuals. Several lens manufacturers aim to provide designs that improve predictability and efficiency in the fitting process. 

Scleral lenses in particular have seen a number of advancements over the past several years. These lenses are intended to clear the cornea and are separated from it by a nonpreserved saline solution. As our knowledge of scleral lens fitting improves, the process has become easier. Here, we discuss the factors that have simplified scleral lens fitting for today’s practitioners.

When Dry Eye Compromises Corneal Integrity

Dry eye disease (DED) affects all parts of the lacrimal functional unit—including the cornea, conjunctiva, meibomian glands, lacrimal glands and the interconnecting innervation. As clinicians, we tend to detect dry eye by listening to patient complaints for DED-related symptoms and closely examining the cornea. This isn’t a misguided approach, considering the cornea is crucial to vision and is often the first structure compromised by DED. 

This article delves into DED’s impact on the cornea, including what we know about the pathophysiology of the condition, the initiating insult and methods of progression.

The Role of Toric Peripheries

Q: I just started fitting scleral lenses but haven’t yet ordered any toric peripheral curve lenses. My lab consultant mentioned that a majority of the orders she gets are for toric peripheries. Most of my patients seem happy and I rarely see much difference in lens edge appearance, but am I missing the point by not ordering toric peripheral curve lenses?
