Abstract Details


The value of IOL material over IOL design in obtaining good visual results and in preventing PCO has been debated for a long time. This study compared two IOLs of the same design and different material, hydrophobic and hydrophilic, implanted in the same patients at the time of cataract surgery.


Ophthalmic Unit, Department of Neurosciences, Hospital and University of Verona, Italy


25 patients scheduled for cataract surgery and with no other ocular disease received the Medicontur 677 AB IOL in one eye (hydrophilic), and the 877 AB IOL in the contralateral eye (hydrophobic). The two lenses share the same design and sharp posterior edge. Patients were followed in the postoperative as for visual acuity. PCO, and aberrations. Current follow-up is 6-30 months.


Visual acuity and refraction did not vary between IOLs. Posterior capsule opacification was very low in this series, and slightly worse for the hydrophobic model. To-date, 3 eyes with the hydrophilic model and 2 eyes with the hydrophobic model underwent laser posterior capsulotomy. The aberration pattern did not vary.


IOL material, hydrophilic or hydrophobic, was completely unimportant in this series of eyes. IOL design appeared to be a more important factor for PCO prevention. FINANCIAL INTEREST: NONE
