The different problems associated to Lasik surgery risks do vary depending on the patient’s overall health condition, plus his/her choice of Lasik surgeon who will perform the surgery. Remember, even though Lasik eye surgery is considered to be one of the safest eye surgery procedures ever to be introduced in any parts of the world, it occurs mostly in reputable Lasik eye correction centers like the Lasik eye surgery Chicagoland center. This eye center is well-known in providing patients only the best laser eye surgery doctors, so consider yourself lucky if you are a Chicagoland-based patient, the risk factors will be surely lessened or eliminated.
Here are some the possible risks for your information:
Development of irregular astigmatism
This is usually possible to patients with uneven shaped cornea, the development of irregular astigmatism. During the Lasik surgery, the laser may not be fully centered on the eye leading to complication of double vision (diplopia). If this problem arises after the Lasik procedure, the eye surgeon may recommend a re-treatment or enhancement surgery. This problem is quite rare with modern-day lasers with their advanced tracking systems that prevent decentration of the laser beam.
There are cases wherein the epithelial cells grow underneath the flap after a Lasik treatment, but this is only self-limiting and not alarming in every sense. If the symptoms of blurry vision or discomfort are felt by the patient due to the epithelial ingrowth, another surgery will be performed to lift the flap and remove the epithelial cells. This problem mostly occurs with unrelated eye trauma not part of the original LASIK procedure but trauma the patient has in the future, again unrelated to LASIK eye surgery.
DLK (Diffuse lamellar keratitis)
Another problem that may be reported after a Lasik surgery is the inflammation underneath the thin flap, leading to DLK which could delay the healing process or worse case scenario is loss of vision. If patient is diagnosed to have developed DLK (diffuse lamellar keratitis) the eye specialist would prescribe the use of antibiotics and other topical steroids. Another procedure will be performed by the eye surgeon which is the lifting and cleaning of the inflamed cells to avoid any tissue damage. With the newer anti-inflammatory eye drops available, this problem is very limited now, but it will occur if patients don’t follow their eye drop regimen as instructed in the postoperative period.
This type of problem is a rare case and could be the result of an unusual bulging of the eye’s surface where too much corneal tissue was removed during a Lasik surgery or when the cornea is very weak before the Lasik treatment. Patient may be fit with gas permeable contact lenses or the eye surgeon will conduct collagen cross-linking to make the cornea stronger. Proper preoperative evaluation to look at corneal shape and thickness as well as proper time out of contact lenses preoperatively will lessen this risk. Any family history of keratoconus can add increased risk to this condition post LASIK surgery.
This is another common side effect associated after a Lasik surgery, but is only a temporary condition and can be remedied through artificial tear solutions prescribed by the eye specialist to maintain the normal level of tear production or a strict compliance of a regulated dry eye therapy is advised to the patient. The good news is that this condition is self-limited lasting only about 6 months postoperatively.
If you want to maintain the lowest possible percentage of risk factor for your upcoming laser eye surgery, ask your eye surgeon if you are really a suitable candidate for the corrective eye surgery type you wish to avail. Don’t forget to verify also the cost of Lasik eye surgery, so that you can prepare in advance all the needed funds for a successful operation.
