When fitting multifocal lenses, many practitioners tell me that they don't need to use the fitting guides as they have better ways to fit the lenses based on their experiences. While I do admit that tips and tricks can be helpful when troubleshooting, I believe it is best to stick to the fitting guide during the initial fitting. These guides are developed through rigorous processes involving numerous patient fits and are designed with this in mind. While you may not be able to fit 100% of your patients, I am sure that you will be able to get at least 70% of them fit and seeing well at a single lens fitting.
Visionary Optics LLC, home of the Europa and Jupiter scleral lenses, announced an enhanced warranty and exchange policy created to alleviate any concerns about using scleral lenses on irregular cornea patients. For parameter adjustments on exchanges and remakes the new policy is: Unlimited Exchanges within 90 days of purchase. If only a parameter adjustment is needed, the original lens does not need to be physically returned. Parameter adjustments required to improve fit, usually made in conjunction with consultation, are acceptable exchanges / remakes. This new return policy is one of several recent improvements that Visionary Optics has made with the goal of making specialty lens fitting and doing business with Visionary Optics an easy choice to make.

Subconjunctival Hemorrhage in Painless Recurrent Red Eye By Carrie Heller, OD, Gainesville, Florida
This is a case of a 24 year-old white female soft contact lens wearer with 2-3 month history of painless recurrent red eye OS. The photo reveals a wedge of her lens embedded under the conjunctiva with one edge abutting a conjunctival vessel causing the subconjunctival hemorrhage.
We thank Dr. Heller for this image and welcome photo submissions from our other readers! It is easy to submit a photo for consideration for publishing in Contact Lenses Today. Simply visit http://www.cltoday.com/upload/upload.aspx to upload your image. Please include an explanation of the photo and your full name, degree or title and city/state/country. ^ Back to top

Ocular Lubrication vs. Bandage Contact Lens in Treatment of Corneal Erosion Syndrome
From the Oxford Eye Hospital in the United Kingdom comes an August 2013 study investigating the efficacy of bandage contact lenses (BCLs) with that of ocular lubricants (OLs) in the initial management of recurrent corneal erosion.
In this randomized controlled small trial of 28 patients with recurrent corneal erosion, the patients were randomized to wear either BCL (for 3 months, replaced every 30 days) or the use of OLs (4x a day with Lacri-lube ointment at night for 3 months). The patients were assessed monthly for 4 months, and their symptoms were graded by visual analog scores. The main outcome measure was the resolution of symptoms with noticeable corneal surface abnormality. Patients with a complete resolution were followed for another 3 months to check for recurrence.
Results of this study demonstrated that BCLs do not increase the likelihood of complete resolution of recurrent erosions when compared with OLs in the initial management of recurrent erosions, however BCL treatment patients experienced earlier relief from symptoms. None of the patients with BCLs developed adverse side effects.1

CARE SOLUTION CORNER Susan J. Gromacki, OD, MS, FAAO
Is Nonpreserved Saline a Prescription Medication? Ask your Pharmacist.
Nonpreserved 0.9% sodium chloride inhalation solution is quickly becoming the standard of care for filling a scleral gas permeable contact lens prior to application. Since it is nonpreserved saline, one would think that it would be available for purchase without a prescription. Well, as Lee Corso might say, "Not so fast, my friend." Several of my local pharmacies (and those of my colleagues from other states) are requiring prescriptions for the solution. But is this correct? For clarification, I contacted a patient of mine who is not only a scleral lens wearer but also a pharmacist. Nurlean Hale-Holman, RPh, informed me that sodium chloride inhalation solution is not a prescription medication and does not require a prescription (at least in Maryland). However, since some pharmacists still ask for a prescription, it is important for you to contact your local pharmacies to find out what their policies are – and to educate the pharmacists on scleral contact lenses.
To simplify the process, I have prepared the following prescription on a preprinted medical Rx pad which I sign and distribute to my scleral contact lens patients.
0.9% sodium chloride inhalation solution
Disp. 3-5 ml vials X 100
Use to fill scleral lens.
The Risk of Microbial Keratitis with Overnight Corneal Reshaping Lenses
The purpose of this study was to estimate the incidence of microbial keratitis (MK) associated with overnight corneal reshaping contact lenses and to compare rates in children and adults.
A retrospective study of randomly selected practitioners, stratified by order volume and lens company, was conducted. Practitioners were invited to participate and those agreeing were asked to provide de-identified patient information for up to 50 lens orders and to complete a comprehensive event form for any of these patients who have attended an unscheduled visit for a painful red eye. Duration of contact lens wear was calculated from the original fitting date or January 2005 (whichever was later) to when the patient was last seen by the practitioner wearing the lenses on a regular basis. Cases of MK were classified by majority decision of a 5-member expert panel.
For the 191 practitioners who could be contacted, 119 (62%) agreed to participate. Subsequently, 11 withdrew, 22 did not respond, and 86 (43%) returned completed forms corresponding to 2202 lens orders and 1494 patients. Limiting the sample to those patients with at least 3 months of documented contact lens wear since 2005 resulted in a sample of 1317 patients; 640 adults (49%) and 677 children (51%) representing 2599 patient-years of wear (adults = 1164; children = 1435). Eight events of corneal infiltrates associated with a painful red eye were reported (six in children and two in adults). Two were classified as MK. Both occurred in children but neither resulted in a loss of visual acuity. The overall estimated incidence of MK is 7.7 per 10,000 years of wear (95% confidence interval [CI] = 0.9 to 27.8). For children, the estimated incidence of MK is 13.9 per 10,000 patient-years (95% CI = 1.7 to 50.4). For adults, the estimated incidence of MK is 0 per 10,000 patient-years (95% CI = 0 to 31.7).
The researchers concluded that the risk of MK with overnight corneal reshaping contact lenses is similar to that with other overnight modalities. The fact that the CIs for the rates estimated overlap should not be interpreted as evidence of no difference. True differences fewer than 50 cases per 10,000 patient-years were beyond the study's power of detection.
