During cataract surgery a circular opening in the front facing capsule of the lens and then removes the inner nucleus. The remaining capsular envelope surrounds the new artificial lens which is typically injected in through the opening in the capsule. Over time the capsule shrinks and wraps around the new lens much like shrink wrap or cling film.
A common natural healing process after cataract or lens exchange surgery, occurs when the thin membrane behind the IOL becomes cloudy or wrinkled. This is called posterior capsule opacification (PCO) or secondary cataract.
PCO usually causes your vision to become blurry, hazy, or glarey again. YAG laser capsulotomy is a safe, in office procedure that permanently clears PCO and improves your vision. It involves using a special laser (YAG laser) to make a small opening in the cloudy membrane, allowing normal light to reach your retina. Treatment only takes a few minutes, is painless and quickly restores your vision to it’s previous clarity.
As PCO only occurs on some but not all cataract patients, it is not included in the price of cataract surgery and has a separate fee (covered by all insurance companies).
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
Your doctor will examine your eyes after instilling dilating drops. If you are found to have PCO then the YAG laser treatement will be offered and this can usually be completed on the same day.
On the day
You will be at Re:Vision for around one hour. Your eyes will be dilated prior to treatment. The procedure itself takes only 2-3 minutes and is completely painless.
Recovery
The recovery following YAG laser capsulotomy is rapid with no pain or discomfort. You can expect your vision to be a bit blurry and light sensitive after YAG laser due to your dilating eye drops. You may prefer a driver to take you home. The next morning you can expect improved vision. You may experience black spots in your vision for a few days but these typically settle with time.
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.

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.
