Visual Outcomes in Ectopia Lentis in Marfan Syndrome: A Study of Four Surgical Techniques in Children and Adults.

: To evaluate how the surgical technique and type of implanted intraocular lens influence the postoperative visual acuity and complications in ectopia lentis associated to Marfan syndrome patients. : The medical records and videos of ectopia lentis surgeries in patients (children and adults) with Marfan syndrome, were retrospectively reviewed and compared. The study included 33 eyes that underwent four different intraocular lens implantation (IOL) techniques: IOL in conjunction with a simple capsular tension ring, IOL in conjunction with a Cionni modified capsular tension ring (m-CTR), two-point scleral IOL fixation and IOL with one haptic in the bag and one haptic sutured to the sclera.

Ectopia lentis surgery in Marfan's syndrome: from "couching" to the use of intracapsular tension rings.

In the course of time, correction of the ectopia lentis in Marfan's syndrome has been approached through quite many surgical techniques. They addressed the iris, or the lens and aimed at increasing the aphakic zone, the opacification or removal of the lens. Although associated to many complications, the first techniques proved the courage and imagination of pioneer surgeons and are worth mentioning.

Enhancing rotational stability of toric intraocular lenses using a type 2L Cionni capsular tension ring in patients with high myopia.

We present the technique used in a patient with high myopia to obtain rotational stability of a plate-haptic multifocal toric intraocular lens (IOL) (AT LISA tri toric 939MP). Both of the patient's eyes had long axial lengths and large capsular bags. The first operated eye experienced consecutive toric IOL malpositions.

Modified bean-shaped ring segments for suture fixation of the bag-in-the-lens intraocular implant.

We describe a surgical technique for secondary stabilization of a bag-in-the-lens intraocular lens (BIL IOL) using 2 modified bean-shaped ring segments in cases of zonular dehiscence associated with pseudophakodonesis. The first modified bean segment is anchored in the sulcus with a suture to the sclera in the area of maximum zonular dehiscence, and the second segment is implanted in the opposite sulcus area. Both segments are placed in the BIL IOL interhaptic groove.

Modified injector for optimal insertion of standard CTRs in lax zonules.

Purpose: Capsular tension rings (CTRs) are commonly used for stabilizing the capsule in lax zonules. Blind and uncontrolled maneuvering of the ring free end may cause intraoperative incidents during CTR insertion. We improved the design of a standard CTR typical injector that eliminates the risks associated with the lack of control during its insertion.
