Advanced Surface Ablation (ASA) is a laser procedure that effectively corrects nearsightedness, farsightedness and astigmatism in most patients through a unique minimally invasive approach. Ideal for patients who are not candidates for LASIK or who are seeking an alternative to the LASIK procedure, this procedure can be performed using several different techniques while providing comparable vision correction results.
Similar to LASIK, there are certain requirements that patients must meet in order to undergo the ASA procedure. This procedure is ideal for patients who:
Advanced surface ablation offers patients significant vision improvement through a safe, minimally invasive procedure that does not require the use of a microkeratome blade and therefore reduces the risk of procedure complications. Many patients are eligible for this procedure and can achieve clear vision with a reduced or eliminated dependence on glasses or contacts without lengthy downtimes.
ASA is efficiently performed on an outpatient basis using only anesthetic eye drops. During the procedure, your surgeon will first remove the surface layer of the eye (epithelium). This can be done with a laser that precisely lifts up part of the surface layer, or with a solution of diluted alcohol that gently loosens the epithelium so that it can be removed or pushed to the side.
Once the epithelium is removed, the cornea is then carefully reshaped with a laser to correct vision. The advanced laser used during this procedure customizes vision correction for each individual patient to ensure successful results. A bandage contact lens is then placed over the eye to promote proper healing.
After the ASA procedure, patients will be able to go home after a short time, although someone will need to drive you home. The bandage contact lens will be worn for three to four days depending on your doctor's instructions. Eye drops will likely be prescribed to prevent infection and keep the eyes moisturized. In most cases, patients can return to work within a reasonable amount of time, depending on their individual condition and their line of work.
Most patients will notice an improvement to vision within the first few days after surgery, with full results usually developing gradually over the course of six months. Glasses may need to be worn during an initial period after surgery as vision adjusts Vitamin supplements may be recommended to help the eyes heal more quickly and comfortably. After surgery, some patients may require follow-up correction treatments in order to maintain the results of their procedure.
It is important for patients to be aware that ASA and other refractive procedures do not correct presbyopia, vision changes brought on naturally as the eyes age. Those who wear glasses prior to treatment will most likely still need reading glasses.
The results of ASA are comparable to LASIK and other laser vision correction procedures, producing significant vision improvement in most cases. Some patients may still require glasses or contact lenses after treatment, but their prescription will be significantly reduced. It is important to note that ASA does not correct presbyopia, the natural change in the eyes that occurs after the age of 40, so older patients will still need reading glasses after surgery.
As with any type of surgical procedure, there are certain risks associated with ASA, including infection, undercorrection or overcorrection and sensitivity to light. These risks are considered rare, and can be further reduced by choosing an experienced surgeon to perform your procedure.
