Advantages and Disadvantages of PRK and LASIK
So you’ve learned about the similarities and differences between PRK and LASIK. Now, let’s take a look at their blessings and disadvantages. Note the following for you might consider a LASIK or PRK eye surgery in the future. Shared Advantages of Both Procedures Both procedures employ excimer laser and with great precision and accuracy, resulting in highly effective vision improvement. More stable vision. No significant drop in structural strength of the eye, which is very necessary for patients at high risk for direct eye trauma. A far greater range of refractive correction than previously available. Advantages of LASIK over PRK Experts found out that LASIK offers more advantages than PRK. Here are some of its advantages: Less postoperative treatment and follow up needed Rapid recovery of visual acuity Little or no postoperative pain. Any initial inflammation after LASIK eye surgery is usually gone by the following morning Capability of simultaneous bilateral treatment. Both eyes are actually treated at the same time. Preservation of common corneal anatomy. It is intriguing to know that the LASIK regimen preserves the epithelium, which is a thin protective layer that covers the cornea. Also, the LASIK regimen preserves the Bowman’s Layer, a structural component just underneath the surface of the corneas that is removed during the PRK procedure. Reduced risk of light sensitivity, which may eventuate for a week or two after PRK. Rapid healing. The protective corneal flap created during LASIK helps alleviate the need for the prolonged medication method required for surface PRK. Shared Disadvantages or Potential Complications of PRK and LASIK Difficulties with eye coordination. This is typical in case when both eyes need correction but only one is operated on initially. With this, there may be troubles with coordination between the corrected and uncorrected eyes. There is a risk of infection in both procedures. Infection is the the bulk serious complication of the bulk eye surgery, and this is extremely rare in LASIK. Blurring of night vision, causing halos or starbursting around bright lights. This is also average in LASIK than in surface PRK. Reduction of best corrected visual acuity. The patient may have much better uncorrected vision, but not as sharp as previous corrected vision. Risk of over or under correction, necessitating continued use of contact lenses or eyeglasses, and possibly more surgery. Laser procedures are the bulk costly than more traditional methods. This is for the fact that both LASIK and PRK involve costly technology and an extensive educational way for the surgeon, laser technicians, as well as surgical assistants. Nevertheless, the bulk patients feel that the increased accuracy, lower re-treatment rate, and alleviated time spent in office visits are well worth the difference in price. Disadvantages or Complications Specific to LASIK The disadvantages or complications of LASIK include troubles with the instrument that makes the flap, the microkeratome, which result in incomplete flaps, irregular flaps, flaps within thin spots or holes in it, or a flap that comes perfectly off. These then call for the regimen to be aborted, and the re-performed in about three months. Occasionally, if scarring develops, the LASIK cannot be repeated and the patient must wear a contact lens for best vision. Also, rarely a flap may call for suturing back in place, and even more rarely, a flap may be lost. This will make LASIK essentially a surface treated regimen with a more variable result and the likelihood of significant corneal scarring. Also, if the flap is lost, a corneal transplant operation may be required. Furthermore, there are some instances that adequate ring suction cannot be maintained, so LASIK cannot be performed. Other uncommon flap troubles may involve undesirable material like cotton fibers in the interface, infection, folds in the flap or epithelial ingrowth underneath it, which requirements repositioning and cleaning of the flap. Today, a lot patients prefer the LASIK regimen over PRK primarily because of the quick vision recovery as well as minimal postoperative care. Many doctors also agree that patients with high amounts of nearsightedness should have LASIK, but for patients with lower to moderate amounts of myopia, either PRK or LSIK may be appropriate. But whatever the case maybe, LASIK is increasingly accepted as today’s standard vision correction surgery procedure. |
