Occlusive IOL
Atrisan lens retro irides
This film shows the technique of implanting an Artisan lens at the back of the iris, thus giving us the benefits of a PCIOL in the absence of posterior capsular support.
Microendoscopic scleral fixation of IOL
A useful video with commentary covering principles of sutured IOLs.
Scleral sutured PCIOL
This is a 50 year old patient with Fuchs Heterochromic iridocyclitis, and glaucoma. She had cataract surgery 20 years ago and a recent trabeculectomy surgery superiorly. Her IOL is both damaged by YAG laser pitting and inferiorly disolcated with poor capsular support. A decision was made to exchange the lens and scleral fixate the new IOL with an aggressive pars plana vitrectomy done to remove significant vitreous inflammatory debris in the hope of reducing chronic inflammation and improving vision. A temporal approach was used because she had over 4 diopters of against the rule astigmatism and to avoid disturbing her filtering bleb. She was very happy with the outcome of this surgery seeing 20/25 at one week post op with a very quiet eye. Please note the importance of a self sealing incision to maintain control of the eye throughout the procedure with the pars plana infusion cannula in place. Also note that a 25 guage infusion line was used with 20 guage vitrectomy with excellent fluidics througout the procedure (bottle height was at 80 during vitrectomy lowered to 40 when the vitrector was removed).
Iris sutured IOL and DSAEK
A surgical video demonstrating the technique for an anterior chamber intraocular lens exchange with a posterior chamber iris-sutured intraocular lens and simultaneous DSAEK.
Artificial iris introcular lens
This surgery is a cataract extraction in a patient with congenital aniridia. An Ophtec articificial iris intraocular lens was implanted.
Crystalens accomodative IOL
This video demonstrates the recommended cataract surgery protocol and insertion of the crystalens accomodating IOL as performed by Jeffrey Whitman, M.D.
Toric IOL (SN60T5)
Edited surgical video of a technique for implanting the Alcon SN60T5 Toric IOL during standard cataract surgery, performed by Richard Prince, with commentary.
Telescopic intraocular lens
The IOL VIP telescopic intraocular lens implant offers an exciting new treatment for dry macular degeneration. IOL-VIP stands for "intraocular lens for visually impaired people".
In this procedure two lenses are placed in the eye. Following standard phacoemulsification , a concave intraocular lens is placed within the capsular bag, effectively acting as the ocular piece of a telescope; and a convex lens is placed in front of the iris in the anterior chamber, acting as the objective lens in a telescope.This system thus creates a Galilean Telescope in the eye, offering a magnification of 1.3x. By rotating the two lenses relative to each other a prismatic effect is also induced, allowing the patient to use an eccentric preferred retinal locus to optimize vision.
Indications include:
Dry age related macular degeneration (Dry AMD)
Stable, inactive or previously treated Wet (exudative) age related macular degeneration
Myopic macular degeneration
Macular holes
Inherited macular diseases such as Best's & Stargardt's dystrophy.
A complex case with penetrating keratoplasty and Verisyse IOL
The surgical management of aphakia with the Artisan/Verisyse IOL in combination with penetrating keratoplasty as well as vitrectomy in cases devoid of any capsular support.
Tetraflex accomodative intraocular lens
The folding and insertion technique for the Tetraflex accomodative intraocular lens.
Marking the eye for toric IOL insertion
This video demonstrates how to mark the cornea prior to implantation of the Alcon AcrySof toric IOL. With the patient sitting upright and looking at a distance target, marks are first placed at the 3:00 and 9:00 positions using a Blakewell BubbleLevel. In the operating room and under the operating microscope, a Gimbel/Mendez fixation ring is aligned with the reference marks. Note that with the patient recumbent, there is about 10° of excyclotorsion. The implantation axis (24°) and the location of the incision (155°) are marked with the Boris Meridian Marker.
Scleral sutured aniridia intraocular lens
The technique for inserting a sutured aniridia intraocular lens. This young patient has significant loss of iris tissue following a previous penetrating eye injury. Corneal repair and pars plana vitrectomy and lensectomy have already been performed.
Insertion of a phakic intraocular contact lens
A nice video showing how to insert a phakic intraocular contact lens. Sounds like an Australian surgeon making the commentary.
