Purpose
To evaluate the performance of an Extended Depth Of Focus (EDOF) Intraocular Lens (IOL) in patients with high myopia.
Setting
AKTINA OPHTHALMOLOGY CENTER
Methods
Twenty (20) eyes without corneal pathology, with presbyopia and over 7 diopters of myopia were enrolled in this prospective study. Mean age was 48.8±12.4 years, the average preoperative refraction was measured to be -12.0 diopters (ranging from -7.0 to -24.5 diopters) with an average axial length of 28.55±2.19mm. All eyes underwent uncomplicated phacoemulsification and were implanted with the same EDOF IOL (Lucidis 124M, SAV-IOL, Switzerland). Swept Source OCT Biometry (Argos, Alcon) with Barrett II Formula was used to calculate IOL power. Ray tracing aberrometry (iTrace, Texas, USA) was used to measure Dysfunctional Lens Index (DLI) and Angle Alpha before surgery and Internal Modulation Transfer Function (MTF) after surgery.
Results
All eyes included in this prospective study had a DLI below 5 and Angle Alpha below 0.2mm. Postoperative refraction after one month was measured to be -0.73±0.68 diopters with 80% of the eyes achieving monocular uncorrected near vision of J3 or better. Internal MTF after surgery, corresponding to the implanted EDOF IOL, was measured to be over 30% at a pupil diameter of 3.0mm in all cases.
Conclusions
Implantation of an EDOF IOL may present a satisfactory solution with predictable outcome in eyes with high myopia and a high axial length, provided suitable technology is utilized for proper calculations. The quality of vision is not significantly impaired; however, monocular uncorrected near vision may seem insufficient in such eyes.
