Dr Loh uses the following lasers:
- Laser Photocoagulation of Retina
- Photodynamic Therapy with Laser of Retina
- Laser of Retina with Binocular Indirect Ophthalmology
- YAG Laser
- Laser Peripheral Iridotomy
LASER PHOTOCOAGULATION OF RETINA
This outpatient procedure is used to treat conditions such as Diabetic Retinopathy, Retinal Vascular Disease, Age-Related Macular Degeneration, Retinal Tears and Paediatric (childhood) Retinal conditions in older children such as Familial Exudative Vitreoretinopathy and Coats’ Disease. Dr Loh currently uses PASCAL (Pattern Scanning Laser) laser as the treatment is faster with less patient discomfort and complications.
PHOTODYNAMIC THERAPY WITH LASER OF RETINA
This is used to treat Central Serous Retinopathy and Age-Related Macular Degeneration associated with specific polypoidal vascular changes. It consists of two steps: (1) injection of Visudyne solution into the vein and (2) applying laser on the retina. When Visudyne is activated by the laser, reactive oxygen product is formed which acts selectively on the abnormal blood vessels. Dr Loh uses Photodynamic Therapy as it is gentler on the eye – the treatment destroys abnormal blood vessel but has less effects on the normal tissues of the patient’s eye.
LASER OF RETINA WITH BINOCULAR INDIRECT OPHTHALMOLOGY
This is used to Paediatric Retinal diseases in babies and young children such as Retinopathy of Prematurity, Familial Exudative Vitreoretinopathy and Coats’ Disease. Dr Loh uses the laser with the least amount of energy and treatment area required so as to minimise effect on the rest of the growing eye.
This used to treat Posterior Capsule Opacification which can occur after Cataract surgery. The capsule holding the new lens is thickened and laser removes the thickened part of the capsule blocking the vision. Dr Loh uses the laser with the least amount of energy required so as to minimise effect on the rest of the eyes.
LASER PERIPHERAL IRIDOTOMY
This is used to treat Angle Closure Glaucoma. The laser creates opening in the iris to prevent sudden increase in intraocular pressure which can affect the optic nerve (nerve of the eye). Dr Loh uses the laser with the least amount of energy required so as to minimise effect on the rest of the eyes.
