A laser eye surgeon is an eye surgeon (ophthalmologist) utilizing the modern technology of a laser device in executing eye operations, usually the removing of cataracts. Eye surgery is also referred to as ocular surgery.
Cataract surgery is generally performed with a phaco probe, which vibrates quickly at ultrasonic frequency and thereby breaks up the cataract while the ensuing particles are sucked up by the probe. In the example of a laser eye surgeon a phaco probe using a laser is used to break up the cloudy lens, which is the cataract and the removal of the fragmented cataract is also done by the probe in a suction action.
Laser eye surgery, generally known as LASIK in the event of cataract removal, requires the patient being administered a tranquiliser drug to induce stillness in the patient before a local anaesthetic is administered to anesthetise the eye. As in any operation procedure, there's always risk associated and in the case of the eye infection is always a risk albeit not a frequent occurrence. Due to this in cataract surgery, only one eye is operated on at once, to limit any probable contamination. The operation generally lasts about one hour and the rate of success of such a procedure is greater than 95%.
The laser eye surgeon performs the procedure in a suitable clean and sterile setting, the area to be operated on is prepared with antiseptics and hand protection and a mask is worn by the laser eye surgeon. A local anaesthetic is administered leaving the individual fully awake (youngsters receive a general anaesthetic) and the laser eye surgeon uses an operating microscope to look into the patients eye. The eye is kept open with a small instrument called an eye speculum, which is inserted under the upper and lower lids and kept open. The laser eye surgeon make use of a laser phaco probe in the one hand and a "chopper" in the other hand to remove the cataract. The cataract is slowly removed by the surgeon making a tiny incision in the lens and the phaco probe is then inserted through the incision to perform phaco emulsification, which is a course of action whereby the cataract is emulsified and sucked up by the probe. When the cataract damaged natural lens has been removed, an intraocular lens (IOL) is placed in position through the tiny cut that had been made at the start of the operation in the cornea. The IOL is an artificial lens made from soft acrylic and it is folded, that enables for easy insertion behind the eye's pupil by a tiny injector. Once placed in position the IOL unfolds and is anchored behind the eye's pupil. Stitches are very rarely required in this procedure, making the recovery process rather fast and painless. A dressing is used and can usually be removed the next day. This procedure provides for speedy vision rehabilitation and often results in less dependence on glasses for distance vision.
In addition there are other procedures or operations done by laser eye surgeons. Some of such procedures are more unpleasant than cataract removal, but are every bit as effective.
