PRK Brochures :
- PRK (photo-refractive keratectomy) has been the most tried and tested form of laser vision correction for more than 30 years and has evolved into the least invasive and safest laser vision treatment for low to moderate shortsightedness and astigmatism.
- Treatment can be delivered without anything touching the eye at all – perfect for those squeamish about their eyes. There is no safer, less invasive vision correction treatment known to man
- A large diameter treatment can be delivered – perfect for patients with large pupils and to optimise night vision
- An extremely smooth treatment is delivered. The smoother the treatment, higher definition vision potential and the less the risk of haze/scarring
- Being flap-free (unlike LASIK or SMILE), this procedure is perfect for patients who may be exposed to blunt injury to their eye/s (police, military, martial arts, rugby, etc). They never need to worry about injuring the corneal flap.
What is Glaucoma?
Glaucoma is a disease that damages the nerve at the back of your eye, called the optic nerve. The optic nerve sends the signals to the brain that enables you to see. Glaucoma is associated with increased sensitivity to pressure within the eye. The eye’s aqueous fluid is constantly produced and drained at a balanced rate and forms the intraocular pressure within the eye (IOP). When this drainage is reduced, or if there is too much fluid production, IOP increases and leads to damage of the optic nerve.

Glaucoma typically has no symptoms. Most patients do not experience any issues until they visit their eyecare provider. Untreated glaucoma can cause a gradual loss of vision, usually starting in the periphery which may go unnoticed for long periods of time.

Our Process :
Assessment
Detailed measurements of the eyes are taken for safety and accuracy, and the team will discuss your options. If you wear contact lenses, please leave them out and wear glasses for two full days prior to the day of your assessment.
Meet your surgeon
Usually, at the same visit, you will meet your surgeon who will thoroughly examine your eyes and discuss your eyesight problems and treatment options.
On the day
You will be at Re:Vision for around two hours. After your procedure which typically takes less than 10 minutes you will be kept comfortable and can choose from a series of snacks. You will need someone to drive you home.
Recovery
The recovery following PRK typically takes a few days. Most individuals have driving standard vision or better within 5 days and can go back to work at this stage. Vision will continue to improve as the surface layer heals over the first 2-4 weeks after treatment.
Check up
Check-up after 4-5 days with most patients going back to work after 5-7 days.
5 most common reasons patients have LASIK eye surgery :
Improved Vision :
LASIK can significantly improve high definition vision, allowing people to see clearly without relying on glasses or contact lenses. This is a huge benefit for people who’ve been struggling with poor vision for years.
Convenience :
For those always on the go or have an active outdoor lifestyle, a life not limited by glasses or contacts is a huge lift.
Cost Savings :
Over time, the cost of glasses and/or contact lenses, all add up. LASIK is a very cost-effective solution to reduce long-term expenses related to vision correction.
Safety :
With advances in laser technology, the small risks associated with LASIK have become increasingly minimal. Risks are minimised by choosing an experienced specialist laser surgeon who uses the latest laser technology.
Improved Self-Confidence :
For many, wearing glasses or contact lenses can be a source of self-consciousness. LASIK helps to improve self-confidence and allow people to feel more comfortable in their own skin.

The benefits of PRK
Safest treatment
There is no safer, less invasive vision correction treatment known to man. It’s therefore a great option for those with a thin cornea. Our surgeons have also published widely on the safety of laser vision correction.
No flap
Being flap-free this procedure is perfect for patients who play contact sports or martial arts.
Precise
It is accepted that this is the most precise way to measure and treat each individual’s unique focus errors.
Better night vision
PRK can deliver the widest treatment diameter – perfect for patients with large pupils and to optimise night vision.
Smooth treatment
An extremely smooth treatment. The smoother the treatment, the less the risk of haze/scarring
Some people are not suitable for PRK surgery and may do better with ICL surgery.
Personalised Surgical Care
Some patients are not suitable for drops or laser therapy and require either cataract surgery, minimally invasive glaucoma surgery or complex glaucoma surgery.
Minimally invasive Glaucoma surgery (MIGS) marks a milestone in the advancement of glaucoma patient care. MIGS are a form of glaucoma surgery which is associated with minimal incisions, and are generally associated with lower risks in restoring normal eye pressure.
Prior to MIGS, treatment options were limited to medications, laser and major glaucoma tube and filtration surgery. Now, with MIGS, our team at Re:Vision have more treatment options which benefits a patient with faster recovery , less surgical risks and less dependence on medications following surgery.
Our surgeon is a leader in MIGS surgery in NZ, with a wealth of experience with iStent -W, Kahook Dual Blade, Hydrus, XEN, Preserflo, micropulse and cyclodiode laser.
MIGS management include:
1) Various treatment options and benefits which are patient centric and individualised
2) Evidence based therapy and
3) Promising outcomes for glaucoma patients.
MIGS can be performed as a standalone procedure or in conjunction with cataract surgery. There are different surgical approaches under the MIGS umbrella, but they generally are designed to allow more fluid to drain out of the eye and hence, reduce intraocular pressure.
a) iStent
The iStent is the smallest medical device ever implanted into humans. The iStent decreases eye pressure by creating a pathway into the eye’s drainage system. The iStent was the first trabecular micro-bypass device approved by the FDA and is the most thoroughly-studied glaucoma device on the market.

b) Kahook Dual Blade
The Kahook Dual Blade goniotomy procedure involves removing a section of the trabecular meshwork (the part which is associated with the greatest resistance in fluid outlflow) and hence increasing drainage out of the eye.

c) Micropulse Laser Treatment
This procedure decreases the amount of fluid produced by the eye and increases fluid outflow. A probe is placed on the surface of the eye and the surgeon applies laser energy to part of the eye which controls the production of fluid in the eye.
d) Preserflo Stent
The Preserflo drainage shunt is type of microshunt implant used to reduced intraocular pressure by creating a controlled pathway for the drainage of fluid out of the eye. It is made from a specialised biocompatible material called SIBS, which is known for its stability, flexibility and compatibility with the human body, hence minimising tissue inflammation.

Trabeculectomy surgery has been done for more than 50 years, and involves making a separate channel for fluid to filter out of the eye.
A drainage tube is a device inserted into the eye, which acts as straw where fluid can access to drain out of the eye onto the outer coat of the eye. There are several drainage tubes available in NZ which include Molteno drainage tube, Paul drainage tube and Baerveldt drainage tube.
Generally, these surgeries are done once all others have been exhausted and have failed to stop the progression of glaucoma.
Glaucoma is optic nerve damage due to increased pressure sensitivity within the eye while a cataract is a clouding of your natural lens within your eye.
In some patients, the hardening and change in the shape of the lens with the development of cataract, can potentiate the effects of glaucoma, such as angle closure glaucoma. In this situation, we may suggest having cataract surgery as a way to treat your glaucoma.
Some patients can combine glaucoma and cataract surgery (includes patients with open angle glaucoma). MIGS procedures in particular can be performed through the same incision as cataract surgery, providing an efficient way to address two problems at once.
World’s most advanced Lasers :
Peramis Wavefront Aberrometer
There are 25 measurable causes of defocus in our eyes. These defocus errors are called aberrations and are precisely measured by an aberrometer. With accurate measuring and laser treatment of these aberrations, we can achieve high-definition vision even clearer than glasses can provide. Older laser technologies, and SMILE, only measure and treat 2 defocus errors, compared to 25. Wavefront aberrometers allow laser surgeons to precisely analyse the optics of the eye. The Peramis aberrometer has six times higher resolution than other systems. This exceptional performance is based on a high-resolution pyramidal wavefront sensor that measures ocular wavefront aberrations with an unequaled 45,000 measuring points. Together with the integrated high-resolution topography with Placido technology, this allows for an extremely accurate assessment of corneal and ocular aberrations. This data allows your surgeon to individually customise the wavefront-based correction of your vision.
Sirius Tomographer
Combines Placido disk topography with Scheimpflug tomography of the front of the eye to allow the surgeon to perform the safest version of laser vision correction customised to your eyes. The device provides highly accurate measurements of corneal thickness, curvature, power as well as pupil size measurements and is commonly used for refractive surgery planning and follow-up.
Schwind Amaris 1050RS excimer laser
Considered the world’s most precise excimer laser for vision correction used in LASIK and PRK. The more precise the laser, the more precise the vision correction. The Schwind Amaris 1050 laser is equipped with 7-dimensional eye tracking for accurate delivery of laser pulses with compensation for the slightest eye movement during surgery.
Smart-pulse technology leaves the smoothest possible corneal surface leading to exceptional visual quality and high-definition vision.
Glaucoma Research at Re:Vision
Dr Perumal values the importance of research initiatives and technology in glaucoma. We may invite you to participate in the Save Sight Registry run by the Save Sight Institute, in collaboration with the University of Sydney and Sydney Eye Hospital to fight glaucoma blindness.
The Save Sight Registries is one of the most advanced ophthalmic registries in the world, and is a unique platform for tracking eye disease, interventions and patient outcomes. Its sophisticated design delivers real-world evidence on the risks and benefits of current and new treatments for ocular conditions. This information helps clinicians provide safe, cost-effective and evidence-based solutions for vision impairment and avoidable blindness.
The Save Sight Registries also promotes international scientific research aimed at developing strategies for reducing the incidence of blindness throughout the world.
