Conditions & Treatments

cataract surgery  

Cataract surgery is a procedure to remove the cloudy lens of your eye and, in most cases, replace it with a clear artificial intraocular lens custom ordered for your refractive measures. Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest cataract surgery.

 

Cataract surgery is very common and is an outpatient procedure, which means you don't have to stay in the hospital after the surgery.

 
Pterygium Excision  

Pterygia are triangular-shaped folds of conjunctiva and fibrovascular tissue that invade the superficial corneal layers. When widespread, they can result in corneal astigmatism or occlusion of the visual field.

 

The surgery is sutureless, using fibrin adhesive to secure the conjunctiva. pterygium is removed and a conjunctival autograft is placed in the area of resection to reduce the risk of recurrence.

 
excisional biopsy of conjunctival tumors  

Ocular surface tumors are rare but potentially deadly diseases of the conjunctiva and/or cornea. The surgical management of any suspicious conjunctival lesion is a complete excisional biopsy of the lesion with cryotherapy to the surrounding conjunctiva and reconstruction.

 
LASIK  

Commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of errors like near and farsightedness and astigmatism.

 

The LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision. This pain-free, scalpel-free procedure eliminates the need for prescription glasses.

 

The average patient can return to work in 1-2 weeks depending on the type of job.

 
Retinopexy  

Pneumatic retinopexy is a surgery to repair certain types of retinal detachments. It is usually an outpatient procedure, which means you don't need to stay in the hospital.

 

Before surgery, your eye is numbed with local anesthesia. Then the ophthalmologist injects a gas bubble into the middle of the eye. Your head is positioned so that the bubble floats to the detached area and presses against the detachment. The doctor then seals the tear in the retina using a freezing probe or laser beam.

 

The bubble helps to flatten the retina until a seal forms between the retina and the wall of the eye. This takes about 1 to 3 weeks. The eye slowly absorbs the gas bubble.

 
Vitrectomy  

Vitrectomy is a surgical procedure undertaken by a specialist where the vitreous humor gel that fills the eye cavity is removed to provide better access to the retina. This allows for a variety of repairs, including the removal of scar tissue, blood, diabetic retinopathy complications, laser repair of retinal detachments and treatment of macular holes. Once surgery is complete, saline, a gas bubble or silicone oil may be injected into the vitreous gel to help hold the retina in position.

 
Intraocular lens  

Intraocular lens (IOL) placement is surgery to put in a new lens in your eye. Your lens is a clear disc located on the front part of your eye. It directs light onto the back of your eyeball. You may need IOL placement if you have problems with your eyesight, such as myopia, hyperopia, or presbyopia. You have myopia if you are nearsighted, which means you have trouble seeing faraway. You have hyperopia if you are farsighted, which means you have trouble seeing up close. Presbyopia is an eye condition where you have a hard time seeing up close as you grow older. You may also need this surgery if your eye has no lens (this is called aphakia).

 
Keratoplasty  

The cornea is the clear layer on the front of your eye that helps focus light so you can see clearly. If it gets damaged, you might need to have it replaced.

 

The surgeon will remove all or part of your cornea and replace it with a healthy layer of tissue. The new cornea comes from people who chose to donate this tissue when they died.

 

A cornea transplant, also called keratoplasty, can bring back vision, lessen pain, and possible improve the appearance of your cornea if it is white and scarred.

 
Trabeculectomy  

Trabeculectomy is a surgical operation which lowers the intraocular pressure inside the eye (IOP) in patients with glaucoma. This is achieved by making a small hole in the eye wall (sclera), covered by a thin trap-door in the sclera. The fluid inside the eye known as aqueous humour, drains through the trap-door to a small reservoir or bleb just under the eye surface, hidden by the eyelid. The trap-door is sutured (stitched) in a way that prevents aqueous humour from draining too quickly. By draining aqueous humour the trabeculectomy operation reduces the pressure on the optic nerve and prevents or slows further damage and further loss of vision in glaucoma. Control of the eye pressure with a trabeculectomy will not restore vision already lost from glaucoma.

 
Ahmed glaucoma valve implant  

Implantation of Ahmed glaucoma valve is an effective surgical technique to reduce intraocular pressure in patients affected with glaucoma. While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases.

 

The valve is made of silicone, and consists of a micro-tube connected to a small end-plate or reservoir. The tube is surgically inserted into the front part of the eye allowing the aqueous fluid from inside the eye to slowly drain through the tube and into the reservoir which is placed on the outside of the eye under the conjunctiva. The fluid is then naturally absorbed by the surrounding tissue. The slow drainage of fluid is not harmful to the eye and decreases the internal pressure. The valve is not visible to the naked eye after surgery.

 
Dacryocystorhinostomy  

Is a procedure that aims to eliminate fluid and mucus retention within the lacrimal sac, and to increase tear drainage for relief of epiphora (water running down the face). A DCR procedure involves removal of bone adjacent to the nasolacrimal sac and incorporating the lacrimal sac with the lateral nasal mucosa in order to bypass the nasolacrimal duct obstruction. This allows tears to drain directly into the nasal cavity from the canaliculi via a new low-resistance pathway.

 
Squint Correction Surgery  

The eye is held open using an instrument called a lid speculum (sometimes it may be necessary to operate on both eyes to get the alignment right). The surgeon detaches part of the muscle connected to the eye and moves it into a new position so that the eyes point in the same direction. The muscles are fixed in their new position with dissolvable stitches.
