Keratoconus Treatment
Keratoconus Treatment
Keratoconus is a progressive eye condition in which the cornea gradually thins and bulges outward into a cone-like shape, leading to distorted and blurred vision. The condition usually affects both eyes and commonly begins in adolescence or early adulthood.
At Eagle Eye Centre, keratoconus is managed in accordance with established Singapore healthcare standards. Treatment is tailored based on disease severity, progression, visual needs, and overall eye health, with the aim of preserving vision and maintaining long-term corneal stability.
What is Keratoconus?
Keratoconus is a non-inflammatory condition that causes structural weakening of the cornea. As the cornea becomes thinner and more irregular in shape, it affects how light is focused onto the retina, resulting in blurred and distorted vision.
Quick facts about Keratoconus
- Progressive thinning and steepening of the cornea
- Usually begins in adolescence or early adulthood
- Can affect one or both eyes
- Early detection allows better treatment outcomes
- Treatment depends on severity and progression
Causes & risk factors
The exact cause of keratoconus is not fully understood. It is thought to be associated with genetic factors, chronic eye rubbing, and certain connective tissue disorders. Environmental factors may also contribute to disease progression.
Symptoms & diagnosis
Common symptoms include blurred vision, increasing astigmatism, sensitivity to light, glare, and frequent changes in spectacle prescription. Diagnosis is made through comprehensive eye examination and specialised corneal imaging to assess corneal shape and thickness.
Treatment options
Treatment for keratoconus depends on the stage of the condition and whether progression is detected. Options may include:
Glasses & contact lenses
In early stages, glasses or soft contact lenses may provide adequate vision correction. As keratoconus progresses, rigid gas permeable or specialty contact lenses may be required to improve visual quality.
Corneal Collagen Cross-Linking (CXL)
CXL is a treatment designed to strengthen the corneal tissue and slow or halt disease progression. It does not reverse existing corneal shape changes but helps preserve vision by stabilising the cornea.
Specialty contact lenses
Customised lenses, such as scleral or hybrid lenses, may be used to improve vision in moderate keratoconus when standard lenses are no longer effective.
Corneal Transplant (Advanced Cases)
In advanced keratoconus with significant corneal scarring or poor vision despite other treatments, corneal transplant surgery may be considered.
Recovery & aftercare
Recovery and aftercare depend on the type of treatment received. Regular follow-up appointments are essential to monitor disease progression, treatment effectiveness, and overall eye health. Patients are advised to avoid eye rubbing and follow their doctor’s care instructions closely.
Frequently asked questions
Ask us anything about how we can help you understand eye care better!
There is currently no cure for keratoconus. However, early diagnosis and appropriate treatment can help manage symptoms, slow progression, and maintain functional vision.
Not all cases progress at the same rate. Some patients experience slow progression, while others may stabilise. Regular monitoring is important to detect changes early.
Medisave eligibility depends on the type of treatment. Some surgical procedures, such as corneal transplant, may be Medisave-claimable subject to Ministry of Health guidelines. Other treatments, including cross-linking and contact lenses, are generally not Medisave-claimable. Patients are advised to check with the relevant governing bodies or their own insurance provider regarding coverage.
Some patients may still require glasses or contact lenses after treatment, depending on the severity of keratoconus and the treatment performed.
You should seek medical advice if you experience frequent changes in vision, increasing astigmatism, or difficulty achieving clear vision with glasses or contact lenses.
