Patients and Methods
Inclusion: Age ≥ 50 years Senile or pre-senile cataract Capsular bag implantation Intraocular lenses from +10 to +30 diopters Potential of corrected visual acuity ≥ 0,6 afer surgery
Exclusion: Amblyopia Monophthalmia History of intraocular surgery in the year before Sequelae of ocular trauma Marked microphtalmos or aniridia History of corneal endothelium damage (caustic burning, herpetic keratitis, cornea
guttata) Astigmatism ≥3.00 diopters IOP ≥25 mmHg with or without treatment Eye disease affecting the visual function (progressive uveitis, diabetic retinopathy,
ARMD, macular dystrophy, retinal detachment, glaucoma, optic neuropathy) Distant patient or difficulty travelling, which makes the clinical follow up difficult Patient involved in another clinical study

Experience with PhysIOL 123
Since the April 2008 to March 2010, 50 IOLs were implanted during
phacoemulsification cataract surgery. All patients were between 50 and 80 years of age (female – 29, male – 21).
In the first 10 cases we used 3.2 mm incisions. In the other 40 cases 2.75 mm clear corneal incisions were utilized.

Experience with PhysIOL 123
The surgery went smooth, with no intra- or postoperative complications. It was very convenient to attach the cartridge with IOL inside to the injector with one click and without any additional manipulations. During the implantation controlled smooth unfolding was observed. We did not observe any adverse effects related to the lens and/or the injection system.
Dr. Mazhry FRCS, FCPS
Conclusion
PhysIOL 123 preloaded IOL system is a surgeon friendly IOL Insertion system in terms of safety, ease of insertion and shortening of overall time spent in the surgical procedure.
