A clear corneal self-sealing tunnel incision was given supero-tempor or temporal depending upon the astigmatism with 2.75 mm keratome, continuous curvilinear capsulorehxis (CCC) performed, lens matter removed with phaco-aspiration and simco cannula, foldable monofocal acrylic non chromophoreintra ocular lens implanted in capsular bag, viscoelastic removed, intracameral moxifloxacin, miochol injected and wound sealed, siedel negative with hydration, making the eye tense (tamponade effect) at the end of surgery to reduce chances of retinal detachment.
Using limbal approach a small entry in cornea was made by 2.8 mm Keratome Sodium Hydrate 1% (Healon) was injected in anterior chamber.
Entry into the anterior chamber is then made through the scleral tunnel with the help of a keratome blade.
The surgeon must operate in the left eye over the back of the patient's nose and eyebrow through SNI, which leads to a steeper angle of approach, particularly during the use of an incision making keratome and phacoemulsification handpiece.
A 3 mm scleral tunnel was generated using a diamond keratome knife (Accutome Inc.
Anterior chamber was then entered with a keratome knife.
Pallikaris and colleagues coined the term LASIK in 1988, a procedure involving corneal ablation by excimer laser under a hinged corneal flap created by an automated keratome. (8) It was thought that by creating an anterior lamellar corneal flap, the integrity of Bowman's layer and corneal neural net is preserved resulting in better healing and predictability, along with reduced pain and corneal haze.
A 3 mm keratome (Alcon Surgicals, Fort Worth, TX, USA) was introduced into the center of the tunnel, and the anterior chamber was entered.
Three-step tunnel incision was given at about 11 O' clock position with 3.2 mm keratome. Anterior chamber was filled with methylcellulose 2%.
In the Phaco 1 technique, the anterior chamber was entered under the scleral flap with a 2.7 mm keratome and after capsulorhexis, phacoemulsification with intraocular lens implantation was performed through this incision.
Lasik involves creating a corneal "flap" of tissue with a mechanical instrument called a Keratome. The flap has a "hinge".
Keratome samples of normal human skin (including both epidermis and dermis) were grafted on severe combined immunodeficient (SCID) mice as previously described.[29] Briefly, keratome strips were cut into 2 x 2-cm pieces and were sutured into place after removal of the same size of mouse skin.
