Presbyopia Correction by Femtosecond Laser-Assisted Cataract Surgery With Trifocal IOL
Narrative Responses:
Purpose
We looked for the decentration of trifocal IOL by using a femtosecond laser for the cataract surgery or clear lens exchange over 6 months. Furthermore we checked the stability of the capsulorhexis over time and the PCO at the anterior capsulorhexis.
Methods
We started with trifocal IOLs in 2011 and combined the procedure since 2012 with a femtosecond laser cataract surgery. We compared in 20 cases the stability of the trifocal IOL in the capsular bag and checked the fibrosis at the anterior capsulorhexis. We looked for the decentration of the IOL over 6 months. We use a 5,5mm femtosecond laser circular capsulotomy and compare this with the manual capsulorhexis. All lenses where implanted in the capsular bag and where implanted over a 2.5mm clear cornea incision.
Results
The study shows that 20% of the manual capsulorhexis shows fibrosis on the anterior capsulorhexis side with a decentration up to 1mm. The other trifocal IOL of the manual procedures shows no decentration and fibrosis on the anterior side. By decentration of the trifocal IOL we found more glare and halos and less visual outcome compared to the other IOLs. By using the femtosecond laser we found no fibrosis on the anterior side of the rhexis and no decentration of the IOL over 6 months.
Conclusion
In our study we found that femtosecondlaser cataract surgery compared with trifocal IOLs is safe and effective for a very good visual outcome by the patients. We found no decentraion and less glare and halo compared to the manual cataract surgery.
