The cyclodestructive effects of cyclocryotherapy and of the neodymium:yttrium aluminum garnet (Nd:YAG) and diode laser transscleral cyclophotocoagulation were investigated in phakic and pseudophakic cadaver eyes using a modified Miyake posterior-view technique and light microscopy. Cyclocryotherapy to -80 degrees C was applied with a 2.5-mm diameter tip, 1 and 2 mm from the limbus. Freezing at ...

PURPOSE To report the results of cataract surgery after previous implantation of an Artisan iris-fixated phakic intraocular lens (pIOL) for the correction of myopia. SETTING University center and private practice. METHODS This study comprised eyes with previous implantation of an iris-fixated pIOL to correct myopia and subsequent pIOL explantation combined with cataract surgery and in-the-b...

purpose: to report clinical outcomes of crystalline lens extraction and iris claw artisan intraocular lens (iol) implantation in patients with lens subluxation secondary to marfan syndrome.  methods: this retrospective study enrolled 14 eyes of 12 marfan patients with lens subluxation who underwent crystalline lens removal and artisan iol implantation. pre- and post-operative data, including pa...

PURPOSE To evaluate the indications, visual outcomes, and complication rate after implantation of a posterior chamber iris-claw aphakic intraocular lens (IOL). SETTING Department of Ophthalmology, University Medicine Charité Berlin, Berlin, Germany. DESIGN Retrospective case series. METHODS Eyes without adequate capsule support had posterior chamber iris-claw aphakic IOL implantation (Ver...

BACKGROUND Nowadays, dislocated intraocular lenses (IOLs) and inadequate capsular support are becoming a challenge for every ophthalmic surgeon. Explantation of dislocated IOL and iris claw IOL (ICIOL) are the techniques that have been used in our ophthalmic department. The aim of this study is to report our technique for retropupillar ICIOL. METHODS This study is a retrospective case series....

AIM To analyse how age-related losses in crystalline lens transmittance and pupillary area affect circadian photoreception and compare the circadian performance of phakic and pseudophakic individuals of the same age. METHODS The spectral sensitivity of circadian photoreception peaks in the blue part of the spectrum at approximately 460 nm. Photosensitive retinal ganglion cells send unconsciou...
