Soft Contact Lenses for Keratoconus Eyes

For quite sometime, the only choice in keratoconus contact lenses is rigid gas permeable lenses.  But now, believe it or not, soft contact lenses are now in the running for contact lens options in managing conic corneas.  What is the difference between the regular off-the-shelves soft lenses to these keratoconus soft contact lenses?  Well, these special lenses are customised, either in material thickness or lens design to enable patients to achieve functional vision.   

Which one is the best for you then?  SCLERAL LENSES vs KERATOCONUS SOFT CONTACT LENSES?   Trial fitting is the key to know which lens is the best for you.  Many considers vision as important, some though look at which type of lens matches his/her lifestyle more.   What is great about scleral lenses is that  this is the best for keratoconus patients with dry eyes as the cornea is constantly bathed in non-preserved saline solution.  And scleral lenses can definitely provide crisper vision even in advanced stage.  However, the customised soft contact lenses can provide more convenience and lesser insertion and removal rituals.    Examples of soft contact lenses for keratoconus are Kerasoft IC lenses and Novakone.  

It is a great time to explore your contact lens options.

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
