Femtosecond Laser-Assisted Intracorneal Ring Segment Treatment (Femto-ICRS)

1. What is Intracorneal Ring Segment (ICRS) Treatment?

Intracorneal Ring Segment (ICRS) treatment is a surgical procedure used to correct corneal curvature disorders and improve visual acuity.This treatment works by inserting ring-shaped implants into the cornea, which alter the thickness and shape of the cornea to enhance vision.

2. Femtosecond Laser-Assisted ICRS (Femto-ICRS):

Femto-ICRS is a type of ICRS procedure in which femtosecond laser technology is used.The femtosecond laser allows incisions to be made with greater precision and predictability, thereby increasing the success rate of the treatment.

3. Femto-ICRS Procedure:

The Femto-ICRS procedure is performed under local anesthesia.The femtosecond laser creates corneal tunnels where the ring-shaped implants will be inserted.These precise incisions ensure that the implants are placed in the correct position.

4. Femto-ICRS and Riboflavin:

During the Femto-ICRS procedure, riboflavin eye drops are applied to the cornea, which is then exposed to ultraviolet (UV) light.The interaction between riboflavin and UV light enhances corneal cross-linking, improving biomechanical stability.

5. Recovery After Femto-ICRS:

The recovery process after Femto-ICRS is similar to that of the traditional ICRS procedure.Patients may experience mild discomfort, redness, and temporary blurred vision.Complete recovery typically takes a few days to several weeks, and following the ophthalmologist’s instructions is essential.

6. Suitable Candidates:

Femto-ICRS is suitable for patients with keratoconus or other corneal curvature disorders.It is preferred when vision cannot be corrected adequately with glasses or contact lenses.

7. Effectiveness and Advantages of Femto-ICRS:

Femto-ICRS enables more precise incisions compared to conventional ICRS.This allows implants to be placed more accurately, improving treatment outcomes.The effectiveness of Femto-ICRS may vary depending on the severity of keratoconus and the quality of postoperative care.

8. Risks and Complications of Femto-ICRS:

Although generally safe, Femto-ICRS may carry risks such as infection, corneal edema, implant displacement, and induced astigmatism.

*Femto-ICRS is an effective method for correcting corneal irregularities and improving visual acuity. However, whether it is suitable for a given patient and the expected outcomes should always be evaluated individually. Therefore, a detailed assessment and adherence to the ophthalmologist’s recommendations are crucial for optimal results.
