Two-year postoperative results of Galand lens implantation

Abstract

The Galand lens is a closed J-loop implant for capsular-bag fixation. We present a retrospective study of 214 eyes implanted with this lens. Eyes were examined at three months, six months, one year, and two years after surgery. Results indicate that 82.2% of eyes obtained a visual acuity of 20/40 or better at two years after implantation. If patients with other ocular pathology were excluded, the percentage of those whose visual acuity was 20/40 or better at two years was 93.7%. Although this implant avoids "spring action" within the capsular bag, the rate of dislocation into the posterior chamber was low (0.93% in this series). Early stability, before sealing of the capsular leaflets, was obtained by limiting the anterior capsulectomy to the pupillary area. No late zonular rupture was observed. Secondary posterior capsulotomy has been performed in 9.8% of the eyes.

Posterior chamber intraocular lens dislocations and malpositions

“…The cause of this condition is an IOL with a diameter that is too short for a particular eye.47 This situation may occur because of an IOL that has been improperly manufactured, so that the tip-to-tip diameter is less than that indicated on the package,4s when an IOL with conventional haptics is placed within a larger, myopic eye,36 if a malpositioned IOL with polypropylene haptics is repositioned without regard to deformation of the hap tic^,^^ and when an IOL with short haptics destined for capsular bag implantation does not fixate within the bag. 50 In addition to the optical consequences induced by a loose IOL, iris chafing with accompanying iritis and/or hyphema can occur. 28 This condition is managed by removing the improper IOL and replacing it with one of appropriate size and h on figuration.^^^^^ Another suggestion is to use McCannel sutures or a modification of this technique to secure the IOL haptics to the iris.30.34.37 Rotating the IOL horizontally and fixing it within the capsular bag are both acceptable ways to reduce the incidence of this malposition.…”

Uncontrolled primary angle closure glaucoma: results of early intercapsular cataract extraction and posterior chamber lens implantation

“…Intercapsular surgery and in-the-bag placement of the PC-IOL, using circular haptics or a disc-type IOL, has made the procedure of cataract extraction in glaucoma patients safer. Placement in the capsular bag has several advantages: the iris-toimplant clearance is maximal, the chance of decentration is very slight, problems from contact between haptic and iris or ciliary body do not exist [4,5,29]. Pigment dispersion glaucoma, hyphaema, iris capture and decentration are all complications which could occur after implanting an expanding flexible J-loop style lens placed in the ciliary sulcus in contact with uveal tissue [1,2,6,15,17].…”
