In Reply.  —We appreciate Dr Friedlander's interesting and practical suggestions. In procedures described in our article and elsewhere1 for external transscleral posterior chamber lens fixation, tying a 10-0 polypropylene suture to the lens haptic may indeed be a difficult maneuver for several reasons. As the polypropylene suture is tied to the lens haptic, the knot may easily slip off the haptic. We have found that a lens recently released by Alcon (Model CZ70BD, Fort Worth, Tex) has holes positioned within the haptics at an optimal site for suture lens fixation, and avoids the problem of knot slippage. The residents in our teaching program have found this lens much easier to use. This lens is also 12.5 mm in length, an ideal length for sulcus placement. As pointed out by Dr Friedlander, tying a one-ended suture may also be challenging. Our technique describes the use of a double-armed polypropylene suture
