"INTRAOCULAR PRESSURE CHANGES AFTER LASER IN SITU KERATOMILEUSIS"
OMNIA FAROUK ABD ELGHANY;
Abstract
There are many refractive procedures modifying the corneal
1 efractive power, some of them present in practice and others are obsolete, one of the most important corneal refractive surgery present in practice is the laser in situ Keratomileusis (LASIK).
LASIK has become a widely spreading and a dominating refractive surgery since 1990s and till now, because it is a safe, effective, and predictable for correction of refractive errors especially for myopia and myopic astigmatism.
Preoperative assessment of the patient as regard to general condition and full ocular examination together with revision of patient visual needs. All are very important steps in achieving an excellent clinical outcome.
In LASIK procedure excimer laser is used to do stromal bed photoablation under a hinged flap which is made by use of microkeratome, and after stromal ablation has done irrigation then drying of the interface, and finally the flap is repositioned carefully to it's ordinary site.
Postoperative use oflocal antibiotics and corticosteroids is a must, but for how long is the use it depends on the outcome of the operation as regard to the postoperative healing or the inflammation if present. Also a soft contact lens is used for only the first postoperative 24 hrs.
As LASIK becomes a popular refractive surgery, ophthalmologists start to give a great interest to it's side effects and also they begin to focus on changes occurring in different corneal parameters like corneal thickness, curvature, and rigidity. And they found a great correlations between some of these side effects and corneal parameters changes. And an example for these con-elations is the significant reduction in intraocular pressure (IOP) values after LASIK when measured by Goldmann applanation tonometry (GAT).
