Initial lamellar resection contraindications may include cornea edema, glaucoma, and keratoconus. Initial lamellar resection risks and complications may include corneal pain, flap tearing, and epithelial ingrowth. IEK contraindications may include any corneal opacity adequately dense to obscure visualization of this iris, descemetocoele with impending corneal rupture, previous corneal incisions that might provide a potential space into which the gas produced by the procedure can escape, and cornea thickness requirements that are beyond the range of the system.
