Laser Treatment

Argon laser (for Diabetic Retinopathy)

Argon laser treatment is to seal up and decrease the fluid leakage from retinal blood vessels to reduce swelling of the macula so as to prevent further loss of vision.

Pan-retinal laser photocoagulation (PRP) prevents new vessels from developing by creating multiple extensive burns at the periphery of the retina to stop any stimulation of the growth of abnormal new blood vessels.

Argon laser (for retinal tear / hole)

Argon laser treatment is carried out if there are holes or tears in the retina. The laser would be applied around these holes or tears. Scar tissue will be formed around the retinal tear or hole sealing it to prevent fluid from entering them and causing a retinal detachment.


Argon laser trabeculopasty  (for glaucoma)

Laser is being applied to the drainage angle to stimulate and increase aqueous fluid outflow and helps lower the eye pressure (IOP).


Peripheral Iridotomy (for Acute angle closure glaucoma)

A hole would be created by a YAG laser at the peripheral iris which creates a new drainage angle to improve the outflow of aqueous fluid. This treatment can be carried out to prevent attacks if one is susceptible to having a close angle attack.



Peripheral Iridoplasty (for glaucoma)

It is a procedure which an Argon laser is used to create contraction burns in the peripheral iris which results in the shrinking of the iris tissue and opening the drainage angle. It is more commonly carried out when peripheral iridotomy was performed but unsuccessful in widening the drainage angle.

Photodynamic therapy (for Age-related Macular Degeneration)

Retinal Laser Photocoagulation

Photodynamic Therapy (PDT) is carried out with a light sensitive drug (verteporfin) and low energy laser to slow down or prevent blood vessels from leaking.


Retinopathy of Prematurity Laser (for ROP treatment)

In advanced ROP, laser treatment is often used to destroy the abnormal vessels on the retina.

It usually causes less inflammation and collateral damage than cryotherapy. It is less painful. There is less myopia and visual results are better.

ROP laser can be done under local anaesthesia (LA) or general anaesthesia (GA). GA is more commonly chosen as there is no pain for the baby. Even under LA, the pain is still quite substantial. Duration of laser is around 1 hour.


YAG Laser (for Posterior capsulotomy)

A non-invasive method of the removal of the lens capsule, pulses of laser energy to create an opening at the centre of the vision.
