Purpose
To evaluate results in cataract eyes trifocal IOLs implantation to provide distance intermediate and near vision.Minimal postop refractive defects provide high quality of vision and patients satisfaction.New center organization and preop eyes evaluation are key points to spread the use of trifocal lenses to the majority of cataract patients
Setting
Piovella Global Center For Ophthalmology, Via Donizetti 24, Monza 20900, Italy
Methods
686 eyes with cataract were implanted with trifocal IOLs.308 eyes(45.04%)with ATLISA tri 839MP-Carl Zeiss Meditec AG Jena and 378 (55.1%) eyes were implanted with AT LISA tri 939MP - Carl Zeiss Meditec AG Jena. Bilateral implant 314 patient, 107 Patients implanted with both TRIFOCAL IOLs(34.1%) 137 Patients implanted with both TORIC TRIFOCAL IOLs (43.6%) 70 Patients implanted with TRIFOCAL IOL in one eye and TORIC TRIFOCAL IOL in the other eye (22.3%) Mean Age 66.49 ±11.66 IOL calculations were performed adopting advanced biometry instruments and astigmatism axis alignment performed with digital system. Tears film quality and MGD was always detected Lipiflow and Blephex were applied routinely
Results
At 6 years monocular Trifocal IOLs results are UCDVA 20/22 ± 2.40 UCIVA 20/24 ± 3.13 UCNVA 20/27 ± 5.37 , monocular Toric Trifocal IOLs are UCDVA 20/20 ± 3.25 UCIVA 20/35 ± 4.75 UCNVA 20/29 ± 2.56 Binocular results (178 patients) are UCDVA was 20/20, intermediate 20/20 and near vision 20/24 96 % OF PATIENTS IN THE RIGHT RANGE (Almost One Eye in the Right Range Sphere Equivalent Within - ±0.50 Sph) Toric IOLs correction is mandatory when 0.75 D of corneal astigmatism is detected. It is necessary to determinate total corneal astigmatism to provide best refractive postoperative outcomes. We have adopted IOL Master 700 TK for the purpose to measure anterior and posterior corneal curvature
Conclusions
AT LISA tri toric 939MP and AT LISA tri 839 MP trifocal IOLs are the most efficient today development of multifocal IOLs family. Clinical outcomes indicate that this is an effective multifocal design to correct refractive defects and to defeat presbyopia after cataract surgery. Data show that it is possible to adopt them in the majority of patients. A new Biometry organization is necessary. Management of MGD support best results in achieving refractive outcomes within -0.50 D postoperatively
