Preliminary results of the new accommodating lens AT-45 from C&C Vision
Neuhann T. H., Okrafka K. P.
Augenklinik am Marienplatz, München
Purpose: To evaluate the possibility of accommodation with a new
design of a silicon intraocular lens.
Method: 38 eyes of 19 patients were implanted with the new flexible
IOL model AT-45. All patients had besides the cataract no other ocular
pathology. After uneventful phacoemulsification through a limbal temporal
incision, 33 IOL were injected through a 3mm incision while 5 IOLs were
implanted with the forceps through a 3.5mm incision. After surgery patients
received beside the topical steroids 1% topical Atropine.
Results: All patients had with BCVA 20/40 or better. Nearvision
is also in all patients above J3 UCVA for distance was due to the new
method an uncertain A-constant between 20/50 and 20/20, while uncorrected
Nearvision was not under J4. All implants centered perfectly, sideeffects
like halos, glare or discoloration of the material were not observed.
Conclusion: The result of our patientgroup shows that a certain
intended movement of the optical part happens, when using Nearvision.
Nevertheless further investigation and refinement in design and surgical
procedure has to be made, to enhance the desired results, which seem to
be possible.
