Lenmed Howick Private Hospital Achieves Milestone with First CAIRS Procedure for Keratoconus

Howick, KwaZulu-Natal, South Africa – March 2026 – Lenmed Howick Private Hospital is proud to announce the successful completion of its first CAIRS (Corneal Allogenic Intrastromal Ring Segments) procedure, marking a significant advancement in specialised ophthalmic care for the region.

The procedure was performed by Dr Davey, Specialist Eye Surgeon, and introduces an innovative, tissue-based solution for patients living with keratoconus – a progressive eye condition where the cornea becomes thin, weakened, and irregular in shape, leading to distorted vision.

A Breakthrough in Keratoconus Treatment

CAIRS is an advanced surgical technique that uses specially prepared donor corneal tissue segments, rather than synthetic implants, to strengthen and reshape the cornea. This natural approach allows for improved compatibility and integration within the patient’s eye.

By restoring a more regular corneal shape, CAIRS can significantly improve visual quality and, in many cases, reduce reliance on glasses or rigid contact lenses.

How the Procedure Works

During the procedure, small arc-shaped segments of donor corneal tissue are carefully placed within the middle layer of the cornea. These segments work to:

• Strengthen the cornea
• Flatten the keratoconus cone
• Improve corneal symmetry
• Reduce irregular astigmatism

The surgery is minimally invasive, sutureless, and performed as a day procedure, typically taking just 20 to 30 minutes.

Transformative Benefits for Patients

CAIRS offers a range of meaningful benefits for patients with keratoconus:

• Improved vision – both uncorrected and with glasses
• Enhanced corneal thickness and shape
• Biological compatibility – using natural donor tissue
• Adjustable and reversible treatment option
• Reduced need for rigid contact lenses
• May prevent or delay corneal transplant in most patients

This procedure is often combined with corneal cross-linking to further strengthen the cornea and stabilise disease progression.

Expanding Access to Advanced Eye Care

The introduction of CAIRS at Lenmed Howick Private Hospital reflects the hospital’s ongoing commitment to bringing cutting-edge medical technology and specialist expertise to the KwaZulu-Natal Midlands.

Early intervention in keratoconus is critical. Innovative treatments such as CAIRS not only improve vision but can significantly reduce the likelihood of requiring more invasive procedures in the future.
