ReLEx (Refractive Lenticule Extraction)


ReLEx is only available at the following centres:

Sheffield Royal Hallamshire Hospital


Relex_ReLEx SMILE(Small Incision Lenticule Extraction) is a ground-breaking new technique that  take laser vision correction for short-sight beyond LASIK. It uses the femtosecond laser to precisely separate and then remove a ‘lenticule’ (a very thin disc) of tissue to re-shape the cornea and change its lens power.

Like LASIK, the corneal surface layer remains largely untouched so ReLEx procedures share the same benefit of minimal post-operative discomfort and rapid visual recovery.  But because no excimer treatment is necessary, the laser procedure itself is quicker: there is no ablation.

ReLEx SMILE has significant added benefits: the corneal surface incision is  dramatically smaller – there is no ‘flap’ so the approximately 20mm cut of LASIK is reduced by more than three-quarters.  Because of this corneal structure is much less compromised so higher prescriptions and thinner corneas may be more suitable for laser vision correction.

The smaller surface involvement also means that corneal sensitivity is much less reduced by treatment: this is the reason that ‘dry-eye’ symptoms are less common after SMILE procedures.

For ReLEx SMILE the treatment day itself is very similar to the other laser treatments.  You will be in the clinic for about an hour, in the treatment room for about 20 minutes.  Your vision will be significantly better the moment that you get up off the couch: after a post-op check and instruction on post-op care, you will be able to go home for a rest.  All ReLEx patients are reviewed the next day and then like the other procedures, at 1 week and then at approximately 1,3,6 and 12 months.
