Description: Information about Trans-PRK (Trans-Epithelial Photorefractive Keratectomy) in Geneva: a 100% touchless surface laser technique, indications, benefits, procedure and recovery. A modern alternative to standard PRK for correcting myopia and astigmatism.

What is Trans-PRK?

Trans-PRK is an advanced form of surface laser vision correction. It is a completely touchless procedure where the excimer laser removes the epithelium and reshapes the cornea in a single step.

The laser performs:

• Epithelium removal (superficial layer),
• Corneal reshaping for visual correction.

This technique is smooth, precise and ideal for patients with thin corneas or those seeking a flap-free procedure.

Which visual conditions can Trans-PRK treat?

• Low to moderate myopia,
• Astigmatism,
• Occasionally mild hyperopia.

Often chosen when LASIK is not suitable.

Trans-PRK vs PRK: what's the difference?

Compared to traditional PRK:

• Trans-PRK: completely laser-based and touchless epithelium removal, more uniform treatment.
• Standard PRK: mechanical or manual removal of the epithelium.

The all-laser approach improves regularity and may reduce early discomfort.

Who is a good candidate for Trans-PRK?

Trans-PRK is particularly suitable for patients who:

• have a thin or borderline cornea for LASIK,
• practice contact sports or high-risk physical activities,
• prefer a no-touch, flapless procedure,
• lead an active lifestyle.

A complete preoperative evaluation is essential.

How the Trans-PRK procedure works

The procedure is:

• Performed under local anaesthesia (eye drops),
• Completely contact-free,
• Done in outpatient surgery,
• Completed with a single-pass excimer laser treatment.

No flap, no mechanical manipulation—only controlled laser precision.

Recovery after Trans-PRK

• Discomfort for 2–3 days (burning, tearing, light sensitivity),
• Blurred vision initially, improving gradually over days to weeks,
• Bandage contact lens removed after 3–5 days,
• Eye drops for several weeks.

Many patients experience smoother early recovery due to the more uniform laser treatment.

Advantages of Trans-PRK

• 100% touchless technique,
• No corneal flap,
• More homogeneous treatment than standard PRK,
• Ideal for thin or irregular corneas,
• Preferred for athletes, military, and high-risk professions.

Risks and limitations

• Several days of discomfort,
• Slower recovery compared with LASIK,
• Risk of corneal haze (rare and preventable),
• Temporary dry eye.

Your ophthalmologist will explain all benefits and potential risks based on your profile.
