Keratoconus

What is Keratoconus(KC)?

KC is a thinning disorder of the cornea causing abnormal bulging of the cornea . As the cornea progressively thins , the patients shortsightedness and astigmatism increases. This leads to frequent spectacle change . Patients often complain of progressive visual deterioration , with ghosting and distortion  of images .This makes daily activities like readings and driving difficult .

Since our motto is FREEDOM for your eyes and you we have successful treatment options available.

KC progression can be successfully stopped with Corneal Collagen Cross Linking procedures. Once the KC has stabilized there are therapeutic options to improve vision and these include : Spectacles , Contact lenses, Intra corneal Ring Segmants , Implantable Collamer lens and therapeutic PRK.

Corneal Cross-Linking (CXL)

CXL is an eye procedure that strengthens the cornea if Keratoconus or even other corneal diseases have weakened it. It involves the application of liquid riboflavin (Vitamin B2) to the surface of the eye, followed by treatment with a controlled application of ultraviolet light, to eliminate corneal ectasia (bulging of the cornea).

ICRS (Intracorneal Ring Segments) implantation

Although Keratoconus can be stabilised with Corneal Cross-linking, some patients are still contact lens intolerant after the treatment and still have poor vision due to a very irregular cornea. We now have a therapeutic option for these patients, namely Intracorneal Ring Segments implantation, called ICRS.

 

ICRS are small arc-shaped rings that vary in thickness and length. They are made of inert plastic which are implanted in a laser cut channel within the cornea. These ring implants cause a flattening of the cone-shaped cornea and subsequently a more regular cornea. It is a safe and effective treatment of Keratoconus and can delay or prevent the need for a corneal transplant. It can also be done in conjunction with CXL.

 

Dr. Sachin Bawa uses a FEMTO laser to create the stromal tunnels to insert the rings, which is a safer and more precise alternative to manual tunnel creation. Each patient will have an individualised treatment plan, based on their corneal maps.

It is performed as a day procedure under topical anaesthesia and patients can resume their normal daily activities the next day.

The Benefits of ICRS implantation

  • It is a minimally invasive procedure
  • Results are rapid and predictable
  • There is a reduced risk of visual adverse effects
  • Provides long-term vision correction
  • It is completely reversible
  • No need for tissue removal
  • Patients are more contact lens tolerant
  • Improves a patient’s quality of life
  • Hight patient satisfaction rate
  • There is a stabilisation or delay of cone progression
  • There is a lack of the cornea rejecting the ring segments due to its acrylic and inert and biocompatible material
  • Can be combined with other procedures such as contact lens fitting, corneal cross-linking, PRK, phakic IOL implantation and intraocular lenses
  • There is no evidence of any interference with a corneal transplant
  • You won’t feel your corneal rings and people wont be able to see them
