About Suitability


Precision Vision – Your Expert in Phototherapeutic Keratectomy (PTK)

Discover the advanced laser treatment, Phototherapeutic Keratectomy (PTK), exclusively offered at Precision Vision. PTK is a cutting-edge laser therapy designed to address various corneal pathologies, focusing on the front surface of the eye. While similar to the more widely known PRK (photorefractive keratectomy), PTK is distinct in its therapeutic application, serving to treat chronic corneal conditions rather than vision correction.

Key Objectives of PTK Treatment:

1. Remove or Decrease Opacities: PTK aims to eliminate or reduce opacities, including blurring, misting, and scarring, which impact visual acuity.

2. Smooth the Corneal Surface: The treatment works to create a smoother corneal surface, enhancing overall eye health.

3. Improve Adherence of the Corneal Epithelium: PTK seeks to enhance the adherence of the corneal epithelium, a crucial aspect for eye function and health.

4. Alleviate Painful Symptoms: Beyond visual improvements, PTK is instrumental in alleviating painful symptoms associated with long-term corneal conditions.

Precision Vision is your trusted partner in offering PTK, delivering a sophisticated and tailored approach to laser therapy. Our skilled team understands the unique needs of each patient, ensuring optimal outcomes in the treatment of chronic corneal pathologies.

Severe blepharitis
Corneal infection


About Treatment Process


PTK surgery does not directly correct the vision but is used to treat the painful symptoms from anterior corneal injuries, scars and removes surface level corneal disease such as corneal dystrophy and epithelial erosion syndrome, which can affect the quality of vision.

The first layer of the cornea (epithelium) is removed using an alcohol solution, and the excimer laser is applied to the eye to remove a minute layer.

In theory, this provides a sounder base layer for healing of the erosion and also allows the corneal epithelium cells to heal all in one “sheet” – this allows for more uniform healing to occur. Following the surgery, a bandage contact lens is put in place to allow healing and reduce pain. There is also a regimen of antibiotic, steroid and pain reducing eye drops that must be followed, as well as the use of moisturising eye drops.

Treatment Process

When arriving at the clinic on the day of surgery our friendly and experienced clinical team will guide you through every step of the way. Prior to the procedure you given a mild oral sedative to help you relax.

The PTK procedure is as follows:

Anaesthetic drops are then applied to numb the eyes. You will be awake and comfortable throughout the procedure
The consultant will then apply an eye lid guard which is used to prevent blinking
The excimer laseris focussed at a particular depth and lasts for only a few seconds
A protective soft contact lens is placed in each eye for 4 days
Your specialist nurse will go through ANY precautions and medications that are needed to aid recovery
Your aftercare will begin 4 days after the procedure

Advanced Control Eye Tracking System

During the consultation a scan and map the entire iris of each eye is performed. Like finger prints, no two irises are the same and a unique digital identification is generated for each eye. It is this map that forms the foundation from which the multi-dimensional eye tracker operates.

Throughout the procedure the Advanced Control Eye-tracking (ACE) system is used, this is a 6-dimensional eye tracker which will guide the laser during the treatment by tracking and mirroring the movement of the eye, and if there is too much movement the laser will shut off.

Before treatment can begin the ACE system has to first recognise the unique ID for the eye being treated. This ensures the treatment profiles are always associated with the correct patient and the correct eye of the patient.

Iris recognition technology ensures accurate placement of your personalised laser treatment
Tracks all eye movements – 6 dimensions (XYZ, intraoperative rotations and static rotations using iris recognition technology)
Takes pictures of the eye (sampling rate) 1,750 times per second (1750Hz)
Has a response time of 2ms – so no laser pulses are ever misplaced
The eye tracker can follow the most sudden or subtle of eye movements

PTK Surgery FAQ’s

Does PTK hurt?

Before the procedure, the surgeon will apply anaesthetic drops to numb your eye so no pain is felt. However, the eye lid guard that prevents blinking throughout the procedure can cause some discomfort.

How much time off work will I require?

Following PTK treatment the majority of patients are back to work within a week. However, this can vary depending on your occupation; working in a dusty environment may mean that more time off is needed. The amount of time off work needed will be suggested at your consultation.

Will my private medical insurance cover PTK?

It is not clear to say whether your private medical insurance will cover PTK, as it is entirely dependent on your policy. You should check over your policy in detail and if you are still unsure, contact your insurance company.

Do you treat both eyes simultaneously?

Yes, we treat both eyes on the same day because of the speed of the treatment.

How is PTK different from LASIK or PRK?

Photo-Therapeutic Keratectomy is a laser procedure that is very similar to the more well-known vision correction surgery known as PRK. Preparation, the procedure itself, and post-op are identical in both types of surgery. The main difference is that in Photo-Therapeutic Keratectomy, no vision correction is done. The main purpose is to treat surface level corneal disease and not to remove the need to wear glasses or contact lenses.

PTK differs from LASIK in two main ways. Firstly, LASIK is performed to reduce spectacle and contact lens dependence, therefore making it a vision correction procedure. Secondly, in LASIK, a flap in the cornea is created. In PTK, no flap is created, making it appropriate for those with thin corneas or dry eye. Also, in PTK no vision correction reshaping of the cornea is done.

What are the risks of PTK?

It is a safe and permanent procedure but like any form of surgery it does have a small amount of risk. These risks include glare, halos, starbursts and light sensitivity.

These are usually mild and tend to disappear over a period of time, although they can be permanent in a tiny number of cases. The surgeon will discuss these with you during the consultation as well as assessing your suitability for PTK.
