Laser vision correction aims to improve the way light is focused in the eye by correcting refractive errors such as myopia, hyperopia and astigmatism. Laser technology reshapes the cornea so that light is focused more accurately on the retina. Suitability for this procedure is determined after a detailed eye examination.
A cataract causes clouding of the eye’s natural lens and can significantly affect visual clarity. During phacoemulsification, ultrasound breaks up the clouded lens, which is then removed through a small incision. An intraocular lens is inserted to help restore the eye’s focusing ability.
Depending on the condition of the eye and the patient’s needs, different types of lenses may be considered.
Types of intraocular lenses:
Monofocal – Primarily provide focus at one distance.
Multifocal – Designed to provide vision at multiple distances.
Trifocal – Designed to provide near, intermediate and distance vision.
Toric multifocal – Combine correction at multiple distances with astigmatism correction.
The lens is selected based on medical assessment, the condition of the eye and the patient’s expectations.
Vitreoretinal surgery includes specialised procedures to treat conditions affecting the vitreous and retina, the light-sensitive layer at the back of the eye. These procedures may be needed for retinal detachment, bleeding inside the eye, pathological retinal changes and other conditions that may threaten vision. The type of surgery depends on the diagnosis and the patient’s condition.
Strabismus is a condition in which the eyes do not move in the same direction. When necessary, surgery aims to adjust the muscles that control eye movement to improve eye position and alignment. The decision to operate is made after an ophthalmic examination and assessment of the degree of strabismus.
DCR, or dacryocystorhinostomy, is a surgical procedure used to treat blocked tear-drainage pathways. This problem can cause persistent tearing, discharge build-up and recurrent infections around the lacrimal sac. During the procedure, a new pathway is created to help tears drain more effectively.
A pterygium is a growth of tissue on the surface of the eye that may extend onto the cornea and cause redness, irritation or vision problems. During surgery, the growth is removed and the affected area is covered with a small graft of tissue, usually taken from the patient’s own conjunctiva. This technique, known as an autograft, helps healing and reduces the risk of recurrence.
A chalazion is a swelling in the eyelid usually caused by a blocked meibomian gland. It can appear on the outer or inner eyelid and may sometimes cause discomfort or pressure on the eye. If it does not resolve with initial treatment or continues to cause symptoms, surgical removal may be recommended following an ophthalmologist’s assessment.
Various lesions may develop on the eyelids and around the eyes, including atheromas, conjunctival and skin cysts, warts and other eyelid growths. Depending on their type, size and location, surgical removal may be recommended to relieve symptoms or treat the lesion. The doctor assesses each growth before the procedure to determine the appropriate treatment.
