The high prevalence of mature, hypermature, and traumatic cataracts in developing countries, combined with the limited availability of surgical resources and skill by anterior segment surgeons to manage the resultant aphakia, leaves the patient needlessly blind. Relying on posterior segment surgeons, expensive surgical setup, and appropriate lenses for aphakia management limits the number of patients receiving a secondary intraocular lens (IOL). Utilizing the well-acknowledged flanging technique and the readily available polymethyl methacrylate (PMMA) lenses with dialing holes in their optic, a hammock can be created through the dialing holes using a 7-0 polypropylene suture on a straight needle. This 4-flanged scleral fixation through the dialing hole of an IOL makes scleral fixation of PMMA lens possible by even anterior segment surgeons without requiring any specialized equipment or scleral fixated lens with eyelet. This technique was successfully performed in a series of 103 cases with no incidence of IOL decentration.
