As several reports have acknowledged, the primary reason why practitioners fit scleral contact lenses today is for the management of keratoconus. There is no doubt that these lens designs have had a significant impact in managing this disease. However, I think it is important to consider the potential impact of other technologies on this trend. For instance, we are concurrently seeing an increase in the use of corneal cross-linking in treating keratoconus. The abstract this week highlights a large multicenter clinical trial of the procedure for keratoconus, showing it to be both safe and efficacious.
Although the procedure is promising, we have managed keratoconus for many years both safely and efficaciously using contact lenses. What remains to be seen is the impact of procedures like this on the contact lens management of keratoconus and other related corneal irregularities. As Dr. Eiden notes in his column below, some surgical procedures can help in very complex contact lens fittings, while some might anticipate that some surgical procedures might reduce the need for complex contact lens fittings for the irregular cornea. Either way you look at it, the future appears bright in that we have many options for managing corneal irregularities going forward.

A 39-year-old Hispanic male presented for a contact lens fitting. His history is significant for a penetrating trauma of the right eye at age 10, resulting in cataract extraction, scleral suture intraocular lens, and vitrectomy. The horizontal corneal scar resulted in flattening of the cornea and a with-the-rule toric corneal topography. The patient was successfully fit with a bitoric GP lens and piggyback soft lens. Vision improved from 20/300 in spectacles to 20/50 with the contact lens.

Synergy of Scleral Lens Management and Oculoplastic Services in Eyecare Practice
The past decade has shown a great increase in the use of scleral contact lenses for the management of irregular cornea conditions, ocular surface disease, and other ophthalmic conditions and diseases. Much closer relationships have been established between those eyecare practitioners who provide advanced scleral contact lens services and subspecialties within ophthalmology such as cornea and anterior segment disease specialists. Attention should also be given to the potential for synergy between scleral lens specialists and oculoplastic specialists. Numerous conditions exist in which these two subspecialties can work together for the benefit of our patients.
A recent article reviewed such a relationship between the contact lens service and oculoplastic service at the University of Iowa.1 The intent of this study was to describe the role and efficacy of scleral contact lenses (SCLs) in the treatment of progressive keratopathy in patients who have undergone periocular surgical procedures; to investigate the financial impact of these surgical interventions; and to demonstrate the role of oculoplastic surgery in improving scleral contact lens fit. A retrospective medical record review was performed to identify patients who both received SCLs and were examined by the oculoplastics service. The indication for SCL use, as well as clinical outcomes of prior oculoplastic treatments and SCL therapy, were recorded for each patient.
During the 25-year study period, 659 patients were fitted with SCLs at the authors’ institution; 43 of those patients were examined by the oculoplastics service for reasons related to their SCL, and 27 of those had surgery. Patients who were fit with SCLs before or after evaluation in the oculoplastics clinic presented with a variety of corneal and periocular pathology. Indications for oculoplastic clinic evaluation in current scleral lens patients included lagophthalmos, trichiasis, epiphora, cicatricial changes in the eyelids or fornices, and eyelid or eyebrow malposition affecting SCL centration. In all of the 27 patients mentioned above, surgical intervention resulted in improved SCL centration. Procedures performed before referral for SCLs included tarsorrhaphies, gold weights, ectropion repair with lateral tarsal strip, retraction repair with spacer grafts, full-thickness skin grafts, cheek lifts, and punctal occlusion.
The authors concluded that scleral contact lenses may offer a useful alternative to stabilize the ocular surface, improve vision, and minimize the financial impact and morbidity of multiple periocular procedures in select patients who have progressive keratopathy of varying etiologies. The therapeutic indications and utilization of SCLs are likely to increase in oculoplastic practices with optometric support, particularly in academic settings. Surgical correction of eyelid and eyebrow malposition, as well as epiphora, may also be useful adjunctive procedures to optimize SCL fit.
I can tell you from my personal experience of having an oculoplastic surgeon join our practice almost three years ago that the impact on our scleral lens service has been remarkable. Our oculoplastic surgeon has referred patients to our associates who fit our scleral lenses to address a number of ophthalmic conditions; respectively, our scleral lens specialists have referred to our oculoplastic surgeon for a variety of surgical procedures. Of special note has been the success of conjunctival chalasis surgery on affected patients in addition to the impact of lid positioning on the fitting of scleral lenses. I urge those of you who are involved in scleral lens management to establish a mutually beneficial relationship with an oculoplastic surgeon. You will be pleasantly surprised with how well such a relationship can work.

OCULAR SURFACE UPDATE
Katherine M. Mastrota, MS, OD
Two week’s time seems to roll around pretty quickly for me these days. I was reminded that I missed my biweekly Contact Lenses Today submission deadline and quickly needed a topic for my contribution. Looking back on my postings, I recognized that I think a lot about eyelashes. We’ve discussed mascara, mascara application, mascara removal, lash growth with lid hygiene, oily lashes, and dry eye blepharitis syndrome (DEBS).
Yet, there is still much to consider regarding all of the “stuff” patients apply to their eyelashes of which we are not aware. This, thereby, forces the question of the impact of these “products” to the eyelashes, lids, and ocular surface.
A walk through the cosmetic counters at any fine department store or health food store will demonstrate the myriad of eye makeup removers available. These products have oils, botanicals, fragrances, and coloring. Solutions/suspensions may be bi-phasic, oily or non-oily, and opaque-looking or clear. Your patient could be using baby oil, coconut oil, olive oil, or petroleum jelly on their lashes. Soaps, creams, lotions, gels, etc.…the list goes on detailing the creative ways that patients (both men and women) clean their lashes (or not).
Please ask what your patients are using for lash hygiene. Let’s create our CLT list to see how many products we can collect.
United States Multicenter Clinical Trial of Corneal Collagen Crosslinking for Keratoconus Treatment
The purpose of this prospective, randomized, multicenter, controlled clinical trial was to evaluate the safety and efficacy of corneal collagen cross-linking (CXL) for the treatment of progressive keratoconus. Study participants included patients who have progressive keratoconus (n = 205). The treatment group underwent standard CXL, and the sham control group received riboflavin alone without removal of the epithelium.
The primary efficacy criterion was the change over one year of topography-derived maximum keratometry value, comparing treatment with control group. Secondary outcomes evaluated were corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA), manifest refraction spherical equivalent, endothelial cell count, and adverse events.
In the CXL treatment group, the maximum keratometry value decreased by 1.6D from baseline to one year, whereas keratoconus continued to progress in the control group. In the treatment group, the maximum keratometry value decreased by 2.0D or more in 28 eyes (31.4%) and increased by 2.0D or more in five eyes (5.6%). The CDVA improved by an average of 5.7 logMAR units. Twenty-three eyes (27.7%) gained and five eyes (6.0%) lost 10 logMAR units or more. The UDVA improved 4.4 logMAR units. Corneal haze was the most frequently reported CXL-related adverse finding. There were no significant changes in endothelial cell count one year after treatment.
The authors concluded that CXL was effective in improving the maximum keratometry value, CDVA, and UCVA in eyes with progressive keratoconus one year after treatment, with an excellent safety profile. CXL affords keratoconus patients an important new option to decrease progression of this ectatic corneal process.
