We present a modified technique for intrascleral fixation of a posterior chamber intraocular lens (IOL) without scleral flaps and assess its long-term safety and efficacy. The haptics of the IOL are externalized with a 23-gauge forceps and fixated in a scleral tunnel. Two clockwise scleral incisions are made using a 23-gauge needle at an angle 30 degrees above the sclera. A 3-piece IOL is inserted into the anterior chamber with an injector through the cornea incision, and the trailing haptic is kept outside to prevent the IOL from falling into the vitreous cavity. The leading haptic is held wit a forceps and extracted from the eye through the scleral incisions. The trailing haptic is held with a forceps and both haptics externalized onto the sclera. The conjunctival incisions are closed with 8-0 absorbable sutures tied to fixate 1 haptic (2 o'clock) after 1 more bite on the scleral bed.

D000867	Anterior Chamber	The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil.

D012590	Sclera	The white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. It is essentially avascular but contains apertures for vessels, lymphatics, and nerves. It receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the CANAL OF SCHLEMM.

D013524	Surgical Flaps	Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.
