LASIK surgery

Phenylephrine is seldom given systemically but is still commonly used as a mydriatic for both diagnostic and therapeutic purposes. Ocular application of phenylephrine 10% in pledget form is used to produce hemostasis in laser-assisted in-situ keratomileusis (LASIK) surgery and other ophthalmic surgical procedures. Phenylephrine is in some countries available in a non-prescription concentration of 0.12% for use as an ocular decongestant. Phenylephrine (up to 10 mg intramuscularly) has similar properties and uses to other alpha-adrenoceptor agonists. 

Ablative photodecomposition (Rangaswamy Srinivasan) Srinivasan s research on ablative photodecomposition leads to multiple applications, including laser-assisted in situ keratomileusis (LASIK) surgery, which shapes the cornea to correct vision problems. 

Lasers are used in a variety of surgical procedures, including cosmetic procedures. LASIK surgery, shown here, is done to improve eyesight. 

In addition to its usual mydriatic effect for diagnostic purposes, phenylephrine has several other clinical uses. The drug can be a valuable aid in breaking posterior synechiae. Application of the 10% solution to the cornea preceded by a topical anesthetic is usually recommended to help break the adhesion. Furthermore, the effectiveness of topical 10% phenylephrine solution is used for peripheral corneal vessel vasoconstriction during LASIK refractive surgery. 

Several studies show that photorefractive keratectomy and laser in situ keratomileusis (LASIK) can induce or exacerbate dry eye. Refractive surgery is believed to cause aqueous-deficient dry eye by a neural-based mechanism. 

Patients with ABMD who have undergone laser in situ keratomileusis (LASIK) may present with visual complaints and/or RCEs. Patients who have signs or symptoms of ABMD may not be ideal candidates for LASIK and should be carefully screened for this condition before pursuing surgery...
