Two patients developed corneal ectasia after photorefractive keratectomy (PRK). Case 1 had evidence of early keratoconus preoperatively, with manifest refractions of -4.00 +2.50 x 160 (20/20) in the right eye and -7.00 +3.00 x 180 (20/30) in the left eye; thin corneas (472 microm and 441 microm, respectively); and inferior paracentral steepening in the right eye and central steepening in the left eye on topography. Case 2 had manifest refractions of -8.50 +3.75 x 123 (20/20(-2)) in the right eye and -9.25 +4.00 x 077 (20/20(-1)) in the left eye; corneal thickness of 509 microm and 508 microm, respectively; and symmetric bow-tie patterns in both eyes on topography. Case 2 had a family history suspicious for keratoconus, with a sibling who had bilateral corneal transplantation at a young age. Both patients developed bilateral corneal ectasia after PRK.

We describe an intraocular lens (IOL) fixation technique that combines suture-in-needle and scleral tunnel techniques. A 10-0 polypropylene suture is inserted into the barrel of a 27-gauge sharp needle to tie the IOL haptic, and scleral tunnels are created to bury the knots for transscleral IOL fixation. The modification of the traditional scleral fixation technique simplifies the creation of a scleral covering and decreases harmful manipulations of the needle passing through the vitreous cavity.

We describe a technique that uses a sliding (Siepser) internal knot to secure the intraocular lens (IOL) and capsular bag complex to the sclera. The technique is helpful in cases of late dislocation of the IOL-capsular bag complex, which seems to be particularly common in patients with pseudoexfoliation. The technique, which borrows from earlier techniques, has the advantages of an external approach of the suture needle and a sliding knot with an internal tie that does not require a knot to be covered or rotated.
