Is Collagen Cross Linking A Must?

We know that keratoconus is a condition that progresses and can lead to possible corneal transplants.  With scleral lenses, indeed we can delay that by still proving functional vision to patients, however, we still believe that collagen cross linking is a must to strengthen the chemical bonds in the cornea.  It is a simple process where the ophthalmologist will expose your cornea to UV light and put riboflavin or Vit B2 drops on it for every few minutes.  This can either be done with the corneal epithelium off or intact.   After the procedure, your corneal collagen bonds will be stronger resisting the fast progression of the cone.  This will give you stability of vision as well.  

Who are candidates for collagen cross linking?

It is best for patients with keratoconus to have this procedure done earlier, before the cornea becomes too irregular and too thin.  

When will it be a good time to wear contact lens again?

Well, it depends on the ophthalmologist who did the procedure.  But normally it would take about 6 weeks to 6 months before we put back your contact lenses.  You see, we need your cornea to completely heal, if we put contact lenses too early, healing will be delayed as you put on and off your contact lenses everyday. So if you need contact lenses to function, then we recommend doing collagen cross linking one eye at a time.

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
