With every medical procedure there is an associate risk. The same applies to laser eye surgery. Be it Lasik or Smile Lasik, either procedure can fail to deliver the expected results demanding a repeat or corrective surgery.
What happens during Lasik treatment?
During laser vision correction procedure, a part of the cornea is removed to reshape the eye surface. The amount of tissue removed depends on the prescription- higher the prescription greater is the tissue removed and vice-versa.
Most surgeons prior to the surgery accurately measure the thickness of the cornea. This is done in an attempt to ensure that sufficient tissue is left behind in the event of re-correction. In cases when there is no remnant thickness to accommodate a re-surgery, the patient is notified.
Repeating a Laser eye surgery:
Yes, the procedure can be repeated in most cases when the patient is unhappy with the results. However, the decision to repeat the procedure is solely in the hands of the surgeon. The doctor will assess the patient’s situation before deciding on the need for re-treatment.
Why opt for retreatment?
If the patient is unhappy with the results of vision correction, he may opt for a retreatment. Although, regression is uncommon affecting only 5% of the total population who undergo Lasik, there will remain dissatisfied patients who want to experience the results they were assured and not compromise for what they’ve received instead.
Complications during retreatment:
* Retreatment of Smile Lasik is generally done using PRK using an excimer to induce slight corrections where needed. Repeating smile is tricky as doubt persists on the location of the incision- the second cut cannot coincide with the first and the nature of new one made- should it be superficial or deep?
* It is important to clarify here that although the procedure or Smile and Lasik are FDA approved, retreatment employing the same is not. The corrective procedures are off record.
* Laser assisted vision correction is not a permanent solution. Patients after 40 can expect to experience blurring of vision. Such incidents cannot be rectified by a re-correction.
In conclusion, most doctors who actively perform Smile and Lasik regard the procedure as highly safe and accurate. The need for re-correction arises in less than 10% of the total cases. When a patient returns for a re-assessment, rectifications are done through minimal manipulations on the prior reconstructed cornea.
