Keratoconus Surgery

Keratoconus treatment plan has two aspects, first to stop its progression, and second to look at the refractive error and provide aid to improve the impaired vision.

After the consultation, our highly trained and trusted cornea specialists evaluate the overall situation and give a solution based on the patient’s eye condition. The following options are available for the treatment of keratoconus.

  • Corneal Collagen Cross-linking (C3R or CXL eye surgery): C3R eye surgery halts the progression of keratoconus.

Key Facts about Crosslinking (C3R or CXL) eye surgery
Crosslinking (C3R or CXL) eye surgery does not correct vision or eliminate the need for contact lens or eyeglasses. It maintains the current level of vision and prevents it from worsening. Crosslinking eye surgery has shown longstanding stability. It is a less invasive treatment than other corneal transplants. Crosslinking surgery aims to strengthen collagen cross-linking strands with the support of riboflavin and ultraviolet rays. It allows for faster recovery and doesn’t necessitate hospitalization.

What Is the Process of Crosslinking (C3R or CXL) eye Surgery

Step 1

During Crosslinking (C3R or CXL) eye surgery, the cornea’s top layer is scraped to instil riboflavin drops and soak cornea for 20-30 min.

Step 2

After this, UV-A radiation exposure is concentrated on the patient’s eyes for 10 minutes.

Step 3

Next, the eye is washed, and a contact lens is placed over the cornea to be worn for 3-4 days.

  • Intracorneal Ring Segments (ICRS):
    ICRS like INTACS, Bio Ring are PMMA ring segments which may be inserted into the corneal stroma to flatten the steep curvature and normalize the corneal shape. This procedure may be combined with C3R to not only stop the disease but also improve the vision as far as possible. ICRS may be performed along with C3R in the same sitting. INTACS are inserted by creating channels in the cornea using the Femto-laser making it a highly advanced and sophisticated procedure. Prior to the procedure, certain investigations like the Pentacam scan need to be done to assess the suitability of the eye and plan the exact location of the ICRS segment in the eyes.
  • Corneal transplantation (Full-thickness or partial thickness):
    For patients with an advanced stage of keratoconus, corneal transplantation may be recommended. This may be a full-thickness procedure called penetrating keratoplasty (PK) or a partial thickness procedure in which only the diseased layer is removed known as Deep Anterior Lamellar Keratoplasty (DALK).

What is Corneal Transplant Surgery or Keratoplasty?

Corneal transplantation or keratoplasty is a surgical procedure where a damaged or diseased cornea is replaced by donor corneal tissue.

Available state-of-the-art options at Centre for Sight for corneal transplant surgery include:

❖ Deep Anterior Lamellar Keratoplasty (DALK), i.e., Partial Thickness Transplant
❖ Full-Thickness/Penetrating Corneal Transplant (PK)

PK (Penetrating Keratoplasty)Deep Anterior Lamellar Keratoplasty (DALK)
Penetrating Keratoplasty is a type of corneal transplantation surgery in which the donor cornea is stitched to the host tissue of the patient. With the recent advancements in surgical techniques and instrumentation, newer kinds of surgeries are done with excellent results. These surgeries are called lamellar transplantation.
It is a conventional procedure being done for many years now.
Penetrating Keratoplasty involves the removal of the entire thickness of the host cornea and replacing it with the donor cornea.
In this type of corneal transplant surgery, only the diseased portion of the cornea is replaced with healthy donor tissue. The rest of the cornea is left undisturbed. When the front portion of the cornea is replaced, it is called as DALK (Deep Anterior Lamellar Keratoplasty).

Keratoconus Eye Surgery Benefits

Most people who undergo keratoconus corneal transplants will have their vision partially restored. But what you can expect after keratoconus surgery depends on your health and the reason for the surgery.
Since risks of complications involved with keratoconus eye surgery continue for years, it is advised to visit a doctor annually for comprehensive eye treatment. Mostly, corneal graft rejections in patients with keratoconus are less common and can be managed with medications.
Once the outer layer of the cornea heals completely after keratoconus eye surgery, our expert eye specialists can make finer adjustments to improve visual acuities like correcting refractive errors through glasses or contact lenses or lasers.
