Abstract Details

Purpose:

Multifocal IOLs are increasingly used to treat presbyopia, well before cataract is present. This study measures visual function and health-related quality of life (HRQoL) after clear lens exchange with multifocal IOLs. We present preliminary results from an ongoing ethically approved clinical multicenter study.

Setting:

This prospective study consisted of a total of 88 subjects who underwent bilateral CLE. We present here interim results from 11 subjects, who had completed one year follow-up. Their mean age was 58 years. Baseline spherical equivalent refraction range was from -7.1D to +2.9D; with mean near add of +2.1D.

Methods:

Of 11 subjects, 5 had bilateral Abbott Tecnis +3.25 bifocals and 6 had bilateral PhysIOL FineVision trifocals with 3 eyes toric versions. Visual function was measured with VF-14 questionnaire before and 12 months after surgery. HRQoL was measured by the 15D instrument. The minimum clinically important change in the 15D score is 0.015 (Sintonen H, www.15d-instrument.net). Use of eye glassed was asked in six step question from 6 as “use all the time” to 1 as “do not need at all”. Baseline BCVA was compared to UCVA in 12 months after surgery.

Results:

VF14 score increased from 79.54 to 98.05 (dimensionless, p < 0.01 compared to baseline). The mean “seeing” dimension score of the 15D improved significantly from 0.82 to 1 (maximum, p < 0.05). The mean overall 15D score increased from 0.914 to 0.940. The change is clinically important, but not statistically significant. Need of eyeglasses decreased significantly also. At 12 month follow-up, UCDVA did not differ from baseline BCDVA in both eyes. Also uncorrected binocular visual acuities to 40 cm, 63 cm, and 100 cm did not differ from baseline values measured with spectacles.

Conclusions:

This interim results show that CLE with multifocal IOLs increase visual functions. There was a clinically important, but statistically non-significant improvement in HRQoL, probably due to a small sample size. Multifocal IOLs demonstrate good near to intermediate visual acuities along with good UCDVA. All the values were in level with pre-operative spectacle corrected measurements. Use of eyeglasses was minimal after surgery.
