  Dear Editor, Top


We read with interest the article "Scleral Suspension Pars Plana Lensectomy for Ectopia Lentis followed by Suture Fixation of Intraocular Lens" by Sandip Mitra et al.[1] The authors mention that their technique involved a three-port sclerotomy opening. That would mean that should a lens fragment dislocate posteriorly, it could be easily removed by a routine vitrectomy. Lensectomy also can be easily done with 2-port sclerotomy, using the infusion port to stabilize the lens.

We see no reason why a prophylactic laser retinopexy should be done at 3 and 9 o' clock meridian, as the scleral fixation sutures pass through the pars plicata. Side effects of laser like macular pucker, retinal or choroidal bleed, etc. are well known.[2] We also feel that vitrectomy should be done before passing the sutures, preventing vitreous entanglement around the sutures, which can later contract and cause problems.

The sutures the authors describe cannot be manipulated other than in the 3 and 9 o' clock axes, thus making it difficult to manipulate a vertically displaced lens, where the movement required is in the 6 and 12 o' clock meridians. These sutures also would probably not stabilize soft lenses and prevent lens drops. In fact, the opening by the sharp needles in the capsule could extend during surgery. Also, presence of sutures within the lens material could also reduce the completeness with which the lens material can be removed.
