Retro pupillary iris claw lenses have been in the picture for the past 40 years, being in and out of favour of cataract surgeons. With improved design, they are proving to be a viable alternative to scleral fixated lenses in the event of a posterior capsular rupture where a posterior chamber lens cannot be placed.
 
In my experience  with  retro pupillary iris claw lenses over the past 2 years, I have a repertoire of over 30 cases which have undergone either a primary or a secondary IOL implantation. The most important advantage with these lenses is that they are placed in a similar position as a posterior chamber intraocular lens hence avoiding the complications of corneal endothelial cell loss. The other important asset of this lens is the relative ease of insertion when compared to a scleral fixated lens.
 
The visual outcome depends primarily on the preceding surgery and the pre-existing complications like pseudo exfoliation. In a patient whose posterior capture rupture has been managed well with a complete vitrectomy the visual outcome is good. The main caveat in the fixation of the lens is proper visualisation of the enclavations, and the use of a lens holding forceps to avoid slippage of the lens, especially while performing the second enclavation. 
 
I have not observed any increased incidence of post operative inflammation as against a posterior chamber intraocular lens, unless in a learner’s hand, excessive handling of the iris has occurred while performing the enclavation.
 
 Hence retro pupillary iris claw lens implantation is a good option in eyes that have had a posterior capsular rupture with no or minimal pupillary abnormalities, affording an excellent visual outcome.

Posterior Iris Claw Lens for Surgical Correction of Aphakia — Long Term Results
Dr. Sreeni Edakhlon, Dr. Abhijeet Khake, Dr. Gopal Pillai S.

Purpose:

To evaluate the safety, technique and efficacy of retropupillary posterior iris fixation of iris claw intraocular lens (IOL) in cases without capsular support.

Method:

100 aphakic eyes with no capsular support underwent retropupillary posterior iris fixation of iris claw IOL Postoperatively best corrected visual acuity (BCVA), astigmatism, intraocular pressure, tissue reaction, pigment dispersion and stability of IOL were studied over three years.

Results:

90% of the cases achieved visual acuity of 6/18 or better. There was no significant change in astigmatism postoperatively. Two IOL’s developed disenclavation and were successfully reenclavated. All the other IOLs were well centered. There was no significant inflammatory reaction or glaucoma. After three years all the enclavated IOLs remained stable.

Conclusions:

Retropupillary posterior iris fixation of iris claw IOL is a safe and effective procedure for correction of aphakia in eyes without capsular support.

In aphakic eyes with no capsular support, the surgical options for optical correction include angle fixated anterior chamber intraocular lenses (ACIOLs), scleral fixated intraocular lenses (SFIOLs) and iris fixated intraocular lenses (IFIOLs). ACIOLs and SFIOLs are associated with significant complications. The most frequent complications in angle fixated ACIOLs are early transient corneal edema,  intraocular  pressure  elevation,  cystoid  macular  edema,  hyphema, secondary  glaucoma,  and  iris  capture  or  pupil  decentration.  In  SFIOLs  the complications include suture erosion, IOL tilting or decentration, fibrin reaction, and vitreous prolapse into the anterior chamber. Also SF IOLs implantation is technically more difficult than AC IOL and the decisive factor in choosing a secondary IOL is surgical experience.1  Posterior iris fixation of  IOLs have the advantage of retropupillary posterior chamber location. They have also been done in children.2  We conducted this study to analyze the stability, safety and efficacy of retropupillary posterior iris fixation of iris claw IOLs in eyes with inadequate capsular support.

To study the long term stability, safety and efficacy of retropupillary posterior iris fixation of iris claw IOLs in eyes with inadequate capsular support.

Non comparative interventional case series.

MATERIALS AND METHODS

One hundred aphakic eyes of one hundred patients with inadequate capsular support for in-the-bag or sulcus placement of posterior chamber intraocular lens were studied. They underwent retropupillary iris fixation of iris claw intraocular lens (IOL) [Excel Optics – Chennai, Model No. PIC 5590] (Authors have no financial interest in the product or this study). The IOL has an overall diameter of 9mm with an optic diameter of 5.5mm and has a 300 claw cut or vaulting for the claws. The estimated A constant is 117.0. Retropupillary posterior iris fixation of the IOLs were done by the same surgeon.

Surgical Technique

Peribulbar anaesthesia was given in all the cases. After automated anterior vitrectomy two paracentesis were made 900 from the scleral section on either side. Intracameral pilocarpine was injected to constrict pupil. Iris claw IOL was introduced into the anterior chamber through a 5.5mm scleral tunnel. Viscoelastic (2% HPMC) was injected at each stage to deepen the anterior chamber and maintain space. Holding the optic with a lens forceps, one haptic was tilted down.
