THIS SCLERAL LENS LOOKS FAMILIAR?

Scleral Lens With Deposits

Does this look familiar? Scleral lenses, similar to other types of lenses are also prone to deposits. This is specially true as the lens does not move much and causes tears to be stagnant behind the lens for a few hours. How to clean this lens? Digitally rubbing the lens with a strong gas permeable solution and cleaner will help. Using AOSept Plus or Clear Care Solution can also aid in everyday cleaning (Note: 6 hours minimum soaking time). Using Progent every 2 weeks will also help clear out stubborn deposits (Special instructions apply). We also encourage patients to use q-tips soaked with saline or gas permeable solution to clean both surfaces every Sunday. This is to be done lightly as not to remove any plasma coating on the lens.

Doing these extra cleaning steps will do wonders for your comfortable scleral lens wear. Scleral lenses do a fantastic job in providing comfort and clarity of vision for patients with keratoconus, pellucid marginal degeneration, post-corneal transplant and other conditions with corneal irregularities.

Can You Do Weight Lifting If You Have Keratoconus?

Many patients are asking if they can still do weight lifting since they have keratoconus. During weight lifting, in order to carry tons of weight, a powerlifter may utilise a breathing pattern which involves Valsalva manoeuvre. According to wikipedia, t he V alsalva manoeuvre is performed by moderately forceful attempted exhalation against closed airway, usually done by closing one's mouth, pinching one's nose shut while pressing out as if blowing up a balloon. Other situations where Valsava manoeuvre is done are during diving, hyperbaric oxygen therapy, air travel and sometimes even going to the restroom doing your number 1. According to Findley, Keating and Toscano (2003), the Valsalva manoeuvre is commonly used in powerlifting to stabilise the trunk during activities such as squat, deadlift, and bench press. So what happens to the cornea when Valsalva manoeuvre is done? A study by Drun et al (2017) recorded the measurements of the corneal curvature,

Can I Drink Alcoholic Beverages While Wearing Scleral Lenses?

Scleral lenses are fitted to patients with complicated prescriptions and irregular corneas. A common question I encountered is "Doc, is it safe to drink alcoholic beverages while I am wearing my scleral lenses?" . Looking into the different papers on the effects of alcoholic beverages on the eye, alcohol, similar to coffee and smoking, can induce some ocular dryness. Studies noted the presence of ethanol in tears of patients within 6 to 12 hours after drinking alcoholic beverages. The presence of ethanol in tears may cause increased evaporation rate, increased corneal staining, and decreased tear volume, leading to dry eyes. Unlike in soft contact lenses, the material of scleral lenses does not undergo dehydration. However, scleral lens wearers may still feel some symptoms of dryness. It is essential, though, to be sure to be still able to remove your lenses when you get home, clean and store them properly. We have one patient who was too drunk

How to Know If Your Keratoconus is Progressing?

Keratoconus typically starts at puberty and progresses until the third or fourth decade of life. At initial diagnosis, younger patients with the steepest corneal curvature (Kmax) of over 55 D have a significantly greater risk of progression. Keratoconus seen at this age is more aggressive, leading to more severe cases. Without any management, the corneal curvature becomes more conical in shape, which can cause worsening of vision, thinning and scarring of the cornea, and possible development of hydrops. However, it tends to stabilize after 20 years from the first diagnosis. To detect keratoconus progression, some corneal parameters need to be evaluated. WHAT THE EYE DOCTOR IS LOOKING FOR? -Increase maximum corneal refractive power (Kmax) by more than 1 Diopter within one year. -An increase in (corneal) myopia by more than 3 Diopter or astigmatism by more than 1.5 Diopter within one year. -An average corneal refractive power increase by more than 1.5 Diopter within one year. -A reduc
