Purpose
To compare binocular visual function between middle-aged patients in their 40s who were in the process of presbyopia progression with unilateral cataract who received either a trifocal intraocular lens (IOL; Alcon PanOptix) or an enhanced monofocal (EM) IOL (Johnson & Johnson Eyhance).
Setting
Hayashi Eye Hospital, Fukuoka, Japan
Methods
This study enrolled patients in their 40s and 50s with unilateral cataract whose fellow eyes were myopic (myopia category) and the operated eyes were implanted with either a trifocal IOL (n = 28, targeting emmetropia) or an EM IOL (n = 28, targeting myopia), and patients whose fellow eyes were emmetropic (emmetropia category) and the operated eyes were implanted with a trifocal IOL (n = 25, targeting emmetropia) or an EM IOL (n = 23; targeting emmetropia). At 3 months postoperatively, binocular uncorrected or distance-corrected VA from far to near distances and binocular contrast VA were compared between patients receiving the trifocal and EM IOLs.
Results
In the myopia category, mean binocular uncorrected VA from ∞ to 1.0 m was significantly better (P < 0.001) and that at near distance was significantly worse (P < 0.001) in the trifocal IOL group than in the EM IOL group. Mean binocular photopic and mesopic contrast VA did not differ significantly between the 2 IOL groups. In the emmetropia category, mean binocular uncorrected VA from ∞ to 2.0 m and mean binocular contrast VA at most contrast levels were significantly better in the EM IOL group than in the trifocal IOL group (P ≤ 0.043).
Conclusions
In middle-aged patients with unilateral cataract whose fellow eye is myopic, trifocal IOLs provide significantly better binocular uncorrected far to intermediate VAs than EM IOLs, suggesting that implantation with a trifocal IOL is preferable. In patients whose fellow eye is emmetropic, EM IOLs provide significantly better far VA and better contrast sensitivity than trifocal IOLs, suggesting that implantation with an EM IOL is preferable.
