Eye Surgery Facts

A surgery performed on the eye or its components is known as an ophthalmologic surgery. If you're curious to know more about this type of surgery read on to discover some eye surgery facts.

Eye Surgery Facts

Basic Eye Surgery Facts

The reason why ophthalmologic surgery is performed on an individual is to correct their vision, to repair defects in the retina or to remove cancer or cataracts in the eye.  Demographics show that patients undergoing eye surgery are either very old or very young patients affected by various eye conditions.  Phacoemulsification for cataracts and elective refractive surgeries are two of the procedures that make these people opt for eye surgery.

An operating room is the place where all the operations take place.  The doctor places all the equipment necessary for the operation in this room.  The tools that one expects to find in an operating room include forceps, blades, scissors, spectrums and scalpels.  Most of the new operating rooms are equipped with lasers, which when used, reduce the operating time as well as the time the patient takes to recover.

For surgeries that last long periods, and require eye specialists, the patient relaxes under the anaesthesia and the surgeon performs the surgery.

Specific Eye Surgery Facts

Refractive surgeries are those that make use of an excimer laser to restructure the cornea.  The surgeon uses the microkeratome, which reduces the time taken for the surgery to several minutes whilst eliminating the need for stitches.  In order to make an opening in the iris and let out the aqueous humour, the surgeon uses the Trabeculectomy technique that is based on a laser technique.  This reduces the intraocular pressure when treating glaucoma.  Wet age-related macular deterioration is treated using the Laser photocoagulation. The advantage with this is that it prevents blood vessels from leaking through burning them.

Eye Surgery Facts Regarding Diagnosis

In the attempt of establishing a diagnosis, the doctor is required to perform a complete patient history, focusing on the patients’ family medical history as well as their vocational vision requirements. Their visual activity is measured under different situations and their overall health is checked since poor health affects ophthalmologic surgery results.

Eye Surgery Facts Regarding Complications

Several complications may arise during the surgery despite the high standard of safety precautions carried by the medical team performing the eye surgery.  Some of the risks include the following:

  • Some patients end up having dry eye, and are treated using artificial tears.

  • Overcorrection or under correction.  During the surgery under correction can be easily treated although overcorrection leaves one having to use contact lenses or eyeglasses.

  • The retina can become loose and detached if the retina is weak.

  • Temporary or permanent debilitating symptoms which include double vision, poor night-time vision and glare.

If the patient has improved vision after surgery, or their vision is restored to what it was before, this situation suggests the so-called “normal results”.

Death during an eye surgery procedure is very rare and in cases where it has happened it tends to be due to the use of local anaesthetic.  The chances of blindness are also there but extremely low.  This is due to the advancements in eye surgery technology.
