1. Refractive Surgery Options
A flapless, minimally invasive laser procedure for myopia and astigmatism using the Visumax 800 femtosecond laser. The laser sculpts a small disc of corneal tissue (lenticule) entirely within the cornea, which is then removed through a small 2–4 mm incision in approximately 8 seconds per eye. This bladeless approach offers high precision, a smaller incision, and faster recovery compared to conventional LASIK.
Uses a femtosecond laser to create a thin corneal flap (20–30 mm incision), which is lifted to expose the underlying corneal stroma. An excimer laser then reshapes the cornea to correct the refractive error, and the flap is repositioned. This well-established procedure is suitable for a broad range of prescriptions.
The original surface laser ablation technique. The outer epithelial layer of the cornea is removed, and an excimer laser reshapes the corneal surface. A bandage contact lens is applied post-operatively to support epithelial healing. PRK is particularly suited to patients with thinner corneas or other contraindications to flap-based procedures.

2. Pre-operative Assessment
Experienced ophthalmic technicians carry out comprehensive refractive assessment and corneal evaluation using modern diagnostic equipment, to determine each patient's suitability for surgery and identify the most appropriate treatment modality.
3. Consultation and Post-operative Care
Cornea and refractive surgery specialists provide personalized treatment recommendations based on each patient's visual needs and corneal profile. The ophthalmic technician and nursing teams are available to address questions at every stage before, during, and after surgery. Structured follow-up visits monitor recovery and guide patients on post-operative self-care and complication prevention.
4. Dedicated Patient Counselor
A patient counselor is assigned to assist from the initial consultation through to post-operative follow-up, providing guidance and facilitating communication across all stages of care.
