| '''IntraLASIK''' is a form of ] similar to ] that creates a ]l flap with a ] ] ] rather than with a mechanical microkeratome, which uses a steel blade. The only difference between LASIK and IntraLASIK (also called 'All Laser Lasik') is the method by which the LASIK flap is created. IntraLASIK can be performed with any ] laser that is able to perform LASIK, including conventional, wavefront-optimized, or wavefront-guided ]. IntraLASIK can be used to surgically create ] to enhance the ability to see objects both distant and near for those affected by ].<ref></ref> | |||

| The term IntraLASIK is derived from ], the name of the first manufacturer to achieve Food and Drug Administration approval of a femtosecond laser for use in the United States, and the surgical procedure 'LASIK'. Although additional femtosecond laser manufacturers have entered the US market, the name IntraLASIK is commonly used. | |||
| A LASIK flap created with a femtosecond laser is regarded by many ]s{{Who|date=July 2007}} as an improvement over traditional LASIK because of a greater accuracy in flap size, shape, and thickness. | |||
| Contradictory information exists as to whether the use of femtosecond lasers in LASIK achieves statistically better ] and ] outcomes than with microkeratomes.<ref>Durrie DS, Kezirian GM. "Femtosecond laser versus mechanical keratome flaps in wavefront-guided laser in situ keratomileusis: prospective contralateral eye study." ''J Cataract Refract Surg.'' 2005 Jan;31(1):120-6.

| Although the final long-term clinical outcome of LASIK with a mechanical microkeratome and IntraLASIK with a femtosecond laser may be similar, the increased accuracy of the flap with the femtosecond laser provides an added margin of safety. LASIK with a flap that is thinner has been shown to provide outcomes superior than a thicker LASIK flap . A thinner LASIK flap requires greater accuracy and predictability. | |||
| A small percentage of IntraLASIK patients develop Transient Light Sensitivity (TLS) which causes severe ] for a period of weeks, however normally resolves with healing and treatment. | |||
| '''FLIVC''' (Femtosecond Laser Intrastromal Vision Correction) is a ] ] technology that is one of several possible alternatives to ] now under investigation. Lower-energy femtosecond lasers may improve upon the traditional excimer laser by reducing disruption of ocular structures, with intrastromal ablation obviating the need for the damaging ] incision and ablation currently employed in LASIK and ] procedures. | |||

It is believed that intrastromal techniques may eventually increase predictability and repeatability of wavefront ablation. Both ] and ] are known to be sponsoring FLIVC studies using their respective lasers. | |||
