Neodymium:YAG laser zonulysis for treatment of lens subluxation.

Nine eyes with lens subluxation in seven patients (6 patients with Marfan's syndrome, 1 with idiopathic lens subluxation) were treated by neodymium:YAG (Nd:YAG) laser zonulysis. The procedure uses an Nd:YAG laser to lyse the zonules to obtain a clear aphakic visual axis. Pretreatment best-corrected visual acuity was 20/60 or worse in eight eyes (6 eyes less than or equal to 20/200). Movement of the crystalline lens was achieved after zonulysis in all cases (100%), and a clear aphakic visual axis, sufficient to maintain aphakic correction without diplopia or glare, was obtained in eight eyes (88.9%). The procedure was combined with optical iridotomy in three cases (33.3%). Five cases (55.6%) required more than one zonulysis treatment. Visual acuity improved two or more Snellen lines in all but one eye (7 eyes greater than or equal to 20/60). Four cases had complications which included: increased intraocular pressure (IOP), mild iritis, recurrent migration of the lens into the visual axis, and crystalline lens damage. The final two complications necessitated eventual surgical removal of the lens. These results suggest that Nd:YAG laser zonulysis may be of benefit as an alternative treatment modality for selected patients with lens subluxation.

Implantation of posterior chamber lenses in eyes with phakodonesis and lens subluxation.

Unilateral posterior chamber intraocular lens (IOL) implantation was performed after phacoemulsification or extracapsular cataract extraction in ten of 11 patients with phakodonesis or lens subluxation, which was bilateral in two cases. To facilitate placement of the IOL, the anterior capsule was opened with a YAG laser in nine patients. Intraoperative vitrectomy was performed in two patients, and posterior chamber IOL implantation was accomplished with fixation in the ciliary sulcus. Postoperative follow-up studies failed to demonstrate significant decentration or dislocation of the IOLs. Phakodonesis and lens subluxation are no longer considered absolute contraindications to implantation of posterior chamber IOLs.

Lens subluxation as a complication of cyclocryotherapy.

There are many well known complications of cyclocryotherapy. This case represents what we believe to be the first report of cyclocryotherapy leading to lens subluxation. The patient was a 14-year-old boy with a history of ocular trauma that had resulted in intractable glaucoma. Six locations were treated inferiorly using the freeze-thaw-freeze technique. Postoperatively the patient's zonular attachment was disrupted inferiorly and the lens subluxated superiorly. While remote trauma may have been partly responsible, we suspect that the cyclocryotherapy precipitated the lens subluxation.

Complications associated with STAAR silicone implants.

We compared the incidence of various complications in consecutive series of cases in which 76 eyes received STAAR silicone intraocular implants and 76 eyes received small incision IOLAB G708G polymethylmethacrylate (PMMA) intraocular implants. All surgeries were performed by the same surgeon employing the same phacoemulsification technique. A higher incidence of lens subluxation, lens repositioning, corneal edema, and elevated intraocular pressure was observed in the eyes receiving STAAR silicone implants than in the eyes receiving IOLAB PMMA implants. In addition, a YAG laser posterior capsulotomy could not be performed through several STAAR silicone RMX 1 model implants. An invasive pars plana posterior capsulotomy was necessary in these eyes. We also found that the STAAR silicone RMX 3 model implants were often pitted by the YAG laser during successful posterior capsulotomies. Despite these problems, the STAAR silicone intraocular lens group achieved corrected vision similar to the PMMA lens group.

Management of the subluxed crystalline lens.

There has been a traditional reluctance to remove a subluxed (ectopic) lens because of the high surgical risk. The use of closed intraocular microsurgical techniques, however, now allows greater intraoperative control with few complications. The authors present the results of subluxed lens extraction, by limbal or pars plana lensectomy, in 44 eyes of 24 patients, in which the indication for surgery was lens subluxation causing a reduction in visual acuity or uncorrectable refractive error. Visual acuity was improved in all cases after surgery, with no significant complications. Patients with reduced visual acuity secondary to ectopic lenses have a good visual prognosis after lensectomy using a closed intraocular microsurgical technique.
