Abstract Details

Purpose:

Femtosecond laser assisted cataract surgery is gaining wide acceptance due to its potential of better safety, predictability and efficacy. Proper centration and positioning of the IOLs is fundamental to achieving improved outcomes possible with premium IOLs. Due to the highly predictable size and position of capsulotomy possible with femtosecond laser, laser assisted capsulotomy can potentially serve as an avenue to improve the centration of the IOL. FEMTIS Laser Lens (Oculentis) has a special haptic system, which allows the lens to clamp into capsulorhexis. This study evaluates up to 12 months outcomes of FEMTIS laser lens implantation in 40 eyes.

Setting:

Augenklinik Bellevue, Kiel, Germany

Methods:

Study included 40 eyes (29 patients) with cataract that underwent femtosecond laser assisted cataract surgery (FLACS). (Mean age 75±8years.) Surgeries were performed by a single surgeon. Femtosecond laser assisted capsulotomy, lens fragmentation, clear corneal cataract incisions were performed using the LENSAR™ femtosecond Laser System. Capsulorhexis was prepared with a diameter of 4.8 mm and was centered at the pupil center. Phacoemulsification was performed with the OS3 phaco system (Oertli, Switzerland). After implantation of the FEMTIS laser lens, ophthalmic viscoelastic device was carefully removed from behind the lens. Afterwards, additional haptics were used to clamp the IOL into the capsulorhexis.

Results:

There were no intraoperative complications in any of the 40 implantations; particularly there was no tearing of the rhexis. After a short learning curve, clamping of the 4 additional haptics into the capsulotomy required minimal additional time. Before clamping the lens into the capsulotomy, the removal of viscoelastic from behind the Femto lens is important. The lens was centered on the rhexis in all cases even in the follow up. Post-operatively, there were no lens-related complications, e.g. no iris capture. The refractive and visual outcomes were comparable to our standard IOL in cataract surgery. DCVA improved from 0.5 to 0.8 postoperatively. The SEQ postoperatively was +0.26.

Conclusions:

The implantation of FEMTIS laser lens was found to be safe and effective during the study follow-up of 1 year. The centering of the lens was maintained on the rhexis and was independent of influences of the capsular bag through the duration of the study. Continued follow-up over longer duration is needed to determine the long-term safety and efficacy of the new IOL. The new IOL design has furthermore the potential for development of new additive IOL which use the haptics in front of the capsulotomy for support.
