Abstract Details

Purpose:

With femtosecond lasers, size and positioning of the capsulotomy can be planned perfectly and reproducibly. That kind of perfection is addressed by a new IOL design for FLACS. The FEMTIS Laser Lens (Oculentis) comes with a special haptic system, which allows additional enclavation of the IOL within the capsulorhexis. Long-term observations are of particular importance for the security of new IOL designs.

Setting:

nordBLICK Augenklinik Bellevue

Methods:

The study shows the results of the FEMTIS Laser Lens in 22 eyes of 16 patients (mean age 75 �Â�± 4.5 years with cataract with a follow-up of 24 months. Capsulotomy and lens fragmentation were performed with the LENSAR laser. Die diameter of the capsulotomy was 4.8�â�€�“5.0 mm and it was centered on the pupil. After implantation of the FEMTIS Laser Lens, the OVD was removed behind the lens and the lens was enclavated within the capsulotomy using the additional haptics.

Results:

There were no intraoperative or postoperative complications. Particularly, there were no capsule tears or iris-captures. The mean implanted lOL power was 20.0 dpt. Visual acuity results were similar to those with our standard IOL for cataract surgery. The mean spherical equivalent was 0.26�Â�±1.69D preoperatively and 0�Â�±0.59D postoperatively. The mean BCDVA improved from 0.5�Â�±0.19 to 0.91�Â�±0.22. The mean IOP (mmHg) was 16.6�Â�±1.7 preoperatively and 13.8�Â�±3.0 postoperatively. No decentrations or unwanted changes related to the anterior capsule enclavation occurred. There was no pigment dispersion caused by the anteriorly positioned haptics.

Conclusions:

The implantation of the FEMTIS Laser Lens turned out to be safe and effective during the follow-up of 2 years. The IOL centration was stable and independent of capsular influence during the study. There were no refractive changes. A longer follow-up is necessary to prove the long term security and stability of the new IOL. The new IOL unlocks a potential for the development of new add-on IOLs which could be fixed to the haptics anteriorly of the capsule.
