Laser eye surgery's safety has been experimented with and assessed by government and military organizations for example the US Navy, the Australian Army, and NASA. Their investigations show that blade-free LASIK (i.e. building a corneal flap with a femtosecond laser) is secure and approved for the SAS, Leading Gun pilots and NASA astronauts.
Professional sportspeople also have used laser eye surgery to make sure their ideal efficiency on the field. This contains sportspeople just like Tiger Woods and David Beckham, whose vision correction procedures undoubtedly permits them to perform at their peak. Despite getting such an exceptional safety profile however, laser eye surgery is nevertheless surgery, and therefore will always have the possible for complications. Such complications are commonly uncommon and generally manageable though, which I will discuss beneath.
LASIK surgery is performed on the eye, an organic tissue. Though the process is particularly accurate, there is an average 3-4% danger the correction might be decent but not completely optimal. In these circumstances, I commonly wait about 3 months to make sure the stability of the residual glasses prescription, then lift the exact same corneal flap designed earlier to 'fine tune' the procedure's outcome. These enhancements are minor corrections, and are hence much more accurate. An incredible advantage of laser eye surgery is the fact that, while extremely stable in the long term, need to everyone experience any refraction shift in their vision; an enhancement including these is usually at almost any time in the future.
Corneal flap matters:
Blade LASIK introduced the threat of producing an abnormal flap (for example a buttonhole flap). Nevertheless, blade-free (femtosecond laser) LASIK eliminates this danger altogether, and resulting from this enhanced safety, it is the only type of laser eye surgery I perform. With blade-free laser eye surgery, inflammation under the flap can often happen (this really is called diffuse lamellar keratitis), and may be managed by an increase in anti-inflammatory eye drops. If cells on the cornea grow (epithelium - a really uncommon occurrence), they are going to generally absorb and disappear. If they ever proliferate, the flap is usually lifted and the offending cells removed.
Temporary dry eye phenomenon is made when the nerves of the cornea are cut, which occurs for the duration of laser eye surgery. It can take about three months for these nerves to regenerate. Throughout this time I would advise replenishing the tear film with lubricating drops.
