New in­no­va­tion in vi­sion cor­rec­tion surgery

The Sun (Malaysia) - - GOOD VIBES -

VI­SION cor­rec­tion surgery, or re­frac­tive and laser eye surgery, is any sur­gi­cal pro­ce­dure to cor­rect vi­sion prob­lems.

Laser-as­sisted in situ ker­atomileu­sis (Lasik) is presently the most per­formed elec­tive pro­ce­dure. In re­cent years, tremen­dous ad­vance­ments have been made in this field and a new pro­ce­dure called ReLEx (Re­frac­tive Len­tic­ule Ex­trac­tion) SMILE (Small In­ci­sion Len­tic­ule Ex­tac­tion) ) is gain­ing pop­u­lar­ity.

Un­like con­ven­tional Lasik, ReLEx SMILE does not cre­ate a corneal flap, and re­quires only one laser (the fem­tosec­ond laser).

In­stead of vapouris­ing cornea tis­sue to cor­rect the un­der­ly­ing short-sight­ed­ness and astig­ma­tism, ReLEx SMILE carves out a small piece of tis­sue called a len­tic­ule in the cornea, which is re­moved through a small key­hole in­ci­sion (about 2.5mm to 4mm).

This en­tire sin­gle-step, all-in-one-laser op­er­a­tion can be com­pleted in about 15 min­utes for both eyes. This laser is fast and uses very low en­ergy. The pro­ce­dure is odour­less and silent, so there is less dis­com­fort for pa­tients.

Pa­tients also feel more com­fort­able be­cause suc­tion on the eye dur­ing treat­ment is gen­tler. There is no fright­en­ing “black­out” or bleed­ing (no red eye) dur­ing the pro­ce­dure, or swelling of the eye af­ter treat­ment.

Due to the smaller wound by min­i­mally in­va­sive surgery, a pa­tient ex­pe­ri­ences less im­me­di­ate post-op­er­a­tive dis­com­fort and tear­ing.

A small in­ci­sion also means fewer corneal nerves are sev­ered dur­ing the pro­ce­dure, which also means less “dry eye”. With no flap cre­ated, dis­place­ment or dis­lodge­ment is not an is­sue.

Most pa­tients will ex­pe­ri­ence a dra­matic im­prove­ment in their vi­sion a day af­ter the surgery, and then re­main sta­ble days af­ter.

How­ever, choos­ing laser eye cor­rec­tion is not a de­ci­sion you should take lightly. All sur­gi­cal pro­ce­dure comes with sur­gi­cal risk.

Have your eyes prop­erly eval­u­ated and ex­am­ined by the eye sur­geon prior to surgery and dis­cuss all op­tions and po­ten­tial risks be­fore mak­ing any fi­nal choices.
