“…A lower overall diameter of 12.5 mm of the NY-60 IOL could explain these findings since the overall diameter seems to influence early rotation. A hydrophobic acrylic lens with a 12.0 mm diameter was found to have rotated slightly more than a 13.0 mm diameter lens in a study of 60 eyes 20. This is in accordance with the low rotation we observed in our study assessing true rotation of a 13.0 mm diameter IOL.…”

“…The AcrySof SN6AT and the Symfony ZXT are 13.0 mm diameter lenses designed with C-loop haptics, In contrast the FineVision POD FT is an 11.40 mm diameter lens designed with double C-loop 4-point-fixation. One should expect that due to the smaller diameter, a higher rate of rotation is expected 14 . The stability provided by the unique double C-loop haptics POD FT TIOLs design may compensate for the smaller diameter and explain our finding 15 .…”

In this study, we retrospectively evaluated the deviation from the planned axis of 3 Toric intraocular lenses (TIOL). Included in the study 190 eyes, operated by two surgeons using two different manual marking techniques. The patients were implanted with either AcrySof IQ Toric SN6AT (Alcon) (n = 90), POD FT (PhysIOL) (n = 50), or TECNIS Symfony Toric (J&J) (n = 50). At least 1 month postoperatively, the IOL was photographed, and the axis was measured using a designed software. The difference between the planned and actual axis was defined as axis deviation. The effect of IOL type, astigmatism direction, and marking techniques on the average degree and direction of the IOL deviation were evaluated and compared. There was no significant difference in the average deviation between the IOLs (TECNIS Symfony: 4.03° ± 4.34, POD FT: 3.52° ± 3.38, and SN6AT: 4.24° ± 4.10), and its direction (55.8%, 39.0%, and 56.6% clockwise (CW) deviation, respectively). With the rule, astigmatism had significantly more CW deviation compared with against the rule and oblique astigmatism (64.3%, 43.8%, and 41.7%, respectively, P = 0.027), but the average deviation was similar. The marking techniques did not influence the degree or direction of the deviation.

“…Optic diameter of IOLs is almost standart due to this limitation. When total diameters are compared, average rotation and stabilization are similar in IOLs with 12 mm and 13 mm total diameters [11] . This parameter does not seem very important in IOL selection.…”

First intraocular lens (IOL) implantation was performed by Dr. Harold Ridley. This first IOL was completely different from the IOLs we use today. IOL technology is one of the fastest developing technologies in recent years in ophthalmology. Monofocal in the bag IOL is the most commonly used IOL according to American Society of Cataract and Refractive Surgery (ASCRS) surveys. In developing countries, use of this IOL are almost standart. There are many different monofocal IOL options on the market and determination of appropriate IOL must be individualized for each patient to reach perfect postoperative outcomes. The aim of this manuscript is to investigate different properties of IOLs on the market in light of evidence based medicine and to give hints about the individualizilation of the IOL selection. For this purpose, our manuscript emphasizes different properties of IOLs and does not refer any trademarks of IOLs.
