Keratoconus is a condition whereby the cornea becomes thin and irregular which causes the cornea to bulge out forming a cone shape.
The definitive cause of keratoconus is unknown, but it is believed to be caused by genetics, inflammation of the eye, rubbing of the eyes, certain disorders, and ethnicity predisposition.
Symptoms of keratoconus varies as the disease progress. It may include blurry or distorted vision, increased sensitivity to light and glare, frequent changes in eye prescription and sudden worsening of vision.

Rose K lenses is a rigid gas permeable contact lenses and is ideal for keratoconus patients as it can be customized to suit each eye and correct both myopia and astigmatism.
The geometry of rose k lenses can be designed to fit well over irregular cornea at different stage of keratoconus and providing better contrast sensitivity and at the same time improve vision with comfort.
Rose K lenses do not cater for presbyopia at the moment. Hence, presbyopic Rose K lenses wearers will need a reading correction glasses over the lenses for reading.
It may be due to eye fatigue or eye strain. It may cause discomfort and tiredness to the eyes when you are doing long hours of computer work, reading, writing or driving.
As Myopia is usually inherited, it may not be preventable. However, we can slow down the progression of myopia with special myopia control glasses or contact lenses. Early detection might be able to delay or avoid the onset and early intervention will have better accumulative efficacy and prognosis of complications.
Progressive spectacle is a popular alternative of bifocal spectacle as there are no distinct lines seen on the lenses. These lenses work by gradually changing the prescription so as to allow wearers to see from distance to intermediate and then to near vision clearly.
An occupational spectacle has similar function as a progressive spectacle, providing mainly clear intermediate and near vision for the wearer. These lenses are ideal for prolong usage of desktop/computer work as the viewing area for intermediate vision is much wider.
Switch to multifocal contact lenses. These lenses provide you with good, functional vision for distance and near vision without having to wear spectacles.
