Purpose: To assess the visual outcome after implantation of the new Hydrophylic IOL type 41 B/G accommodating intraocular lens (AIOL). Methods: The presented lens was implanted during cataract surgery. All patients were offered follow-ups, allowing two postoperative measurements to be performed at 3 months and between 2020 and 2021. The mean time between lens implantation and last follow-up was 5.3 years (min. 1 year, max. 10 years). Excluded were patients with age-related macular degeneration or amblyopia. Patients with a foreign lens implanted into the second eye were included in a separate control group. Corrected distance (CDVA) and uncorrected distance visual acuity (UDVA) at 5 m, and corrected near (CNVA) and uncorrected near visual acuity (UNVA) at 40 cm were assessed. Furthermore, the postoperative spherical equivalent (SE), the dependence on spectacles and the occurrence of optical phenomena were evaluated. Results: The final study cohort consists of 65 patients with 119 implanted AIOLs. Significantly better visual results were obtained in both postoperative follow-ups compared with the preoperative results. The mean values of the last follow-up for the UNVA, CNVA, UDVA, and CDVA were 0.107 ± 0.10;0.039 ± 0.08;0.097 ± 0.11;and 0.040 ± 0.09 logMAR, respectively. Visual outcomes remained on a high level for up to 10 years and showed significantly better results compared to the control group. Postoperative SE was significantly improved. Nearly 70% of patients were no longer dependent on glasses. Furthermore, the occurrence of disturbing optical phenomena was denied by all patients. Conclusion: The results of this AIOL are particularly promising, especially since gratifying visual results could still be measured 10 years after implantation.

Background The TetraFlex accommodating intraocular lens （IOL） was designed to supply the patients both satisfied far and near vision after cataract *** we need to evaluate the safety, distance and near visual acuity, subjective accommodation and IOL mobility with the TetraFlex accommodating IOL *** Fifty eyes of 42 study-eligible cataract patients, who gave informed consent at a single eye clinic in China over a 10-month period, underwent phacoemulsification with TetraFlex IOL *** three months postoperation,uncorrected visual acuities （UCVA）, best corrected visual acuities （BCVA）, distance-corrected near visual acuities （DCNVA）, subjective accommodation using the defocus method, and pilocarpine-induced IOL mobility were *** No postoperative complications were noted in the *** months postoperation UCVA and BCVA were 20/40 or bettter in 82% （41/50） and 92% （46/50） of eyes, respectively; 66% （33/50） of the eyes had DCNVA of Jager （J） 4or better at 3 *** addition, the mean subjective accommodation was （0.94±0.61） diopters （D）（range from 0.50 to 1.50 D） and pilocarpine-induced IOL mobility was （337±124） μm （range from 121 to 501 μm） with the *** relationship （r2=0.901, P 〈0.01） was found between these two *** Implantation of the TetraFlex is safe and leads to excellent uncorrected distance vision and good uncorrected near vision.

Presbyopia still remains the last frontier of refractive *** surgical management is under constant evolution due to the limitations that exist today with respect to its management,which is probably in relation with the multifactorial basis in which presbyopia is clinically developed in the *** currently,virtually all surgical techniques that have been proposed for its correction are based on the induction of pseudoaccommodation in the presbyopic eye,including ***,the real restoration of accommodation is more complex,and it has been tried by the use of different,so called,“accommodative”pseudophakic intraocular lenses(AIOL).Overall,the reported results with these lenses by independent authors have been modest in relation with the restoration of the accommodative power of the eye and these modest benefits are usually lost with time due to the long term changes in the capsular *** fact made these lenses to be almost abandoned in the last few years,but there are currently other AIOL models being used with innovative mechanisms of action and different anatomical support outside the capsular bag that offer encouraging preliminary results that could bring a new potential of application to these types of *** this article,we will update the modern refractive surgeon about the fundamentals and provide updated information about the outcomes of AIOLs by reviewing the concept of accommodation,the different attempts that have been accomplished in the past,their demonstrated published results in human clinical trials,and the future alternatives that may arrive in the near future.
