RESUMO
Purpose: To evaluate the visual outcomes and efficacy of astigmatism correction using a new hydrophobic trifocal toric intraocular lens (IOL). Methods: This study involved 62 eyes implanted with the FineVision HP Toric IOL. The visual and refractive outcomes were assessed preoperatively and 6 weeks after the surgery. Specifically, monocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA) at 80 and 60 cm and uncorrected near visual acuity at (UNVA) at 40 cm were evaluated. The rotational stability of the lens was also assessed. Results: Sixty-one eyes (98.39%) were within ±1.00D and 55 eyes (88.71%) were within ±0.50 D of spherical equivalent, with a mean value of 0.09±0.39 D. 51 (82.26%) and 61 (98.39%) eyes had a UDVA of ≥20/20 and ≥20/25, respectively, and for CDVA these values were as follows: 59 (95.16%) and 62 eyes (100%), respectively. The mean UDVA and CDVA were 0.01±0.06 and -0.01±0.04logMAR, respectively. Greater than or equal to unaided 20/20 vision was achieved at 40 cm in 42 (67.74%), UIVA at 60 cm in 42 (67.74%) and 50 eyes (80.65%) at 80 cm. Those achieving ≥20/25 were 56 (90.32%, 40 cm), 59 (95.16%, 60 cm), and 62 eyes (100%, 80 cm). Postoperative mean values were 0.04±0.07, 0.03±0.07, and 0.00±0.07logMAR for UCNVA, UIVA at 60 cm, and UIVA at 80 cm, respectively. The mean rotation of the IOL was 5.8 degrees. Conclusion: This hydrophobic trifocal toric IOL provides good refractive outcomes with excellent visual acuity across multiple distances, providing a full range of focus.
RESUMO
PURPOSE: To compare ultrasound time (UST) during femtosecond laser-assisted and conventional cataract surgery or refractive lens exchange and evaluate UST during femtosecond laser surgery with and without a new technique, translenticular hydrodissection. SETTING: Centre for Sight, East Grinstead, West Sussex, United Kingdom. DESIGN: Comparative case series. METHOD: This single-surgeon study compared consecutive femtosecond laser-assisted surgery (with and without translenticular hydrodissection to assist lens mobilization) and consecutive conventional surgery performed immediately before adoption of femtosecond laser technology. The mean US power, UST, and effective phacoemulsification time (EPT) in the 2 groups were compared. Further analysis of the femtosecond group compared translenticular hydrodissection and no translenticular hydrodissection. RESULTS: The mean US power, UST, and EPT were significantly longer in the conventional group (n = 108) than in the femtosecond group (n = 108) as follows: 7.30% ± 2.56% (SD) versus 5.32% ± 2.48% (P=.000); 9.89 ± 5.32 seconds versus 8.58 ± 4.66 seconds (P=.044); 0.87 ± 0.85 seconds versus 0.57 ± 0.51 seconds (P=.002), respectively. In the femtosecond group, parameters were significantly higher in eyes without translenticular hydrodissection (n = 27) than in eyes with translenticular hydrodissection (n = 81) as follows: 5.78% ± 2.23% versus 5.16% ± 2.56% (P=.046); 10.95 ± 4.66 seconds versus 7.78 ± 4.41 seconds (P=.046); 0.72 ± 0.26 seconds versus 0.52 ± 0.53 seconds (P=.002), respectively. CONCLUSION: Femtosecond laser capsulotomy and lens fragmentation statistically significantly reduced UST over conventional surgery. Translenticular hydrodissection further reduced UST.
