Functional Outcome After Implantation of New Aspheric Trifocal Len
Narrative Responses:
Purpose
To evaluate the visual outcomes after trifocal IOL implantation.
Methods
This retrospective study comprises results after bilateral implantation of trifocal aspheric intraocular lens (IOL) in 60 Patients. Each eye was documented postoperatively seven days, binocular exams followed after 1 and 3 month after surgery. Subjective refraction (SR), defocus curve (DC), contrast sensitivity (CS), halos & glare assessment (HGA) and a patient questionnaire were documented.
Results
3 month postoperative spherical equivalent resulted in -0.05 ± 0.04 and average UCVA was 0.0 logMAR. The respective defocus curve showed 2 peaks for near- & far distance VA. IV was represented by a pleateu instead of a peak at around 70 cm with a decimal visus of 0.05 ± 0.01 logMAR. CS was comparable to CS of phakic younger patients at certain spatial frequencies. Photopsia like halos and glares were remarkably low: starburst and rings occurred in almost all cases, but with an average size and intensity of less than 30% of the maximum possible.
Conclusion
Considering life style of patients in case of a computer-based daily routine, as well as handcraft or night driving, the trifocal lens accomplishes patients’ needs better compared to the former bifocal generation IOL including tricky light conditions, especially in younger patients. All patients are able to conduct nocturnal car trips.
