If you suffer from dry eyes, red eyes or conjunctivitis, make an urgent appointment to consult your eye doctor.

Approximately 50% of the world’s population requires some form of vision correction. In 1993, it was estimated that 50 million people worldwide choose to wear contact lenses as the primary means of obtaining clear vision.
Laser eye surgery is considered a significant development in ophthalmology over the past three decades. Several types of lasers may be used on different parts of the eye and have been helpful in treating many different types of eye diseases and conditions.

The term “LASER” is an abbreviation for “Light Amplification by Stimulated Emission of Radiation.”
Various types of ophthalmic lasers are used to treat different types of eye conditions. Ophthalmic lasers are named according to the material contained in their plasma tube source.
In the most commonly used ophthalmic lasers, a powerful electric current is passed through a tube containing one of several gases (Argon, Krypton or Argon Fluoride) or a solid material (neodymium-YAG, Q-Switched). Light Energy is produced and the laser emits a small uniform light beam which, when focused through a microscope or other lenses, produces either heat coagulation, tissue cutting, or ablates/evaporates certain eye tissues – as per the need of the patient.
OLDER Argon gas lasers emit a green or blue-green light beam, and is used to treat retinal or iris tissue, while the Krypton gas laser emits a red or yellow light beam to be used for treating other types of retinal conditions. Both are less frequently used nowadays.
Solid state crystal lasers and diode lasers are commonly available too, and have other specific applications.
NEWER Q-Switched and YAG Lasers are more widely used to treat retina and iris tissue conditions, as well as separating/breaking thin membranes.
Excimer (Excited Dimer) Laser is used during LASIK and PRK/Epi-Lasek/LASEK surgeries for vision correction and enhancement of previous similar surgeries.
Femto-Second Lasers are used to separate layers of clear tissue so as to create corneal flaps for LASIK, Pockets for Corneal Inserts and Reshaping (SMILE), and entry wounds for corneal & cataract surgery and corneal grafts, as well as lens fragmentation for cataract surgery.
The ophthalmic laser allows patients to be treated without the risk of infection, in a relatively painless way with minimal discomfort, on an outpatient basis. With their sophisticated microscopic focusing and delivery systems, ophthalmic lasers provide the ophthalmologist with precision and control not previously available with other surgical techniques. This precision, safety, convenience, and reduced cost allows more people to be treated successfully for an increasing number of eye disorders and diseases.
1. Diseases of the retina
People with diabetic retinopathy may not suffer reduced vision in the early stages, and therefore regular eye examinations by an ophthalmologist are important, especially for people who have been diabetic for a number of years. Uncontrolled diabetes mellitus causes accelerated diabetic damage to the retina, leading to vision loss – earlier than what the average diabetic patient may encounter.
2. Glaucoma
In untreated cases, the nerve of sight (optic nerve) becomes damaged due to the buildup of fluid pressure inside the eye that remains too high for too long. Fortunately, loss of vision from glaucoma can be prevented or limited most of the time if the disease is detected and treated before noticeable damage occurs to the optic nerve. Glaucoma, more than any other eye condition, needs to be detected early if treatment is to be successful, and vision loss to be limited.
The laser is used to create a tiny opening – iridotomy – in the peripheral iris of the eye to allow the ocular fluids to circulate better and reduce acute pressure rises and the development of optic nerve damage. Surgical intervention with iridotomy and cataract extraction may assist in the control of the intraocular pressure, if it proves to be necessary and appropriate.
