Comparison of Silicone Hydrogel Daily Disposable Multifocal Contact Lens (MyDay daily disposable Multifocal) |

MyDay MF Clinical Study |

109 |
|
The mean age of the 109 patients enrolled in the study was 51.2 years (lowest: 43 years, highest: 64 years). Gender: 5 males (4.6%) and 104 females (95.4%). History of ophthalmic surgery: 1 case, ocular complications: 2 cases, and complications of allergic diseases: 10 cases were observed, but none of them had any problems with lens wear. The most common lifestyle habits in the study subjects' daily lives were, in descending order, cell phone/smart phone use (96.3%), housework (93.6%), driving a car or motorcycle (74.3%), computer use (69.7%), and close work such as desk work (62.4%). The proportion of the eyes corrected with a spherical power of -3.00D to -5.75D in the previous lenses was 63.9% for 1day disposable single vision lenses, 48.4% for multifocal silicone hydrogel lenses, and 45.7% for multifocal hydrogel lenses. Moderate myopias were observed the most in this study subjects. The percentage of CL corrected patients with binocular distance visual acuity of 1.0 or better was 85.2% for the 1day disposable single vision lenses, 96.9% for the multifocal silicone hydrogel lenses, and 91.3% for the multifocal hydrogel lenses, while the percentage of CL corrected patients with binocular near visual acuity of 1.0 or better was 33.3% for the 1day disposable single vision lenses, 34.4% for multifocal silicone hydrogel lenses, and 21.7% for multifocal hydrogel lenses. |

Seven minor and non-serious adverse events were observed in six patients. In these 7 cases, "foreign body sensation (both eyes)" was found to have a relationship with the study lens, "superficial punctate keratitis (both eyes)" and "subconjunctival hemorrhage (right eye)" were unknown cause, and the other four cases of "subconjunctival hemorrhage (right eye)," "poor physical condition," "chalazion (right eye)" and "Upper eyelid meibomian gland infarction (left eye)" were all evaluated as not related to the study lens. One case of "liquid leakage" was reported, but no adverse events were observed due to this problem. |

Primary endpoint: Overall satisfaction with the study lens as measured by the Visual Analog Scale (VAS) The mean +/- standard deviation of the VAS value at Visit 4 (overall satisfaction with the study lens) minus the VAS value at Visit 2 (overall satisfaction with the previous lens) for the 109 study subjects was 0.74 +/- 25.90, with a median (interquartile range) was 1.0 (23.0). A histogram was generated and a Shapiro-Wilk normality test was performed. p=0.0034 was obtained, so the Wilcoxon signed rank test was used. The results of this two-tailed test showed that p=0.5589, which did not prove the superiority of overall satisfaction with the study lens compared to the previous lens. The results of the subgroup analysis also failed to prove the superiority of overall satisfaction with the study lens compared to any of the previous lenses. Secondary endpoint: Overall evaluation score for ease of handling the study lens The median (interquartile range) of the overall evaluation score in Visit 4 (ease of handling the study lens) minus the overall evaluation score in Visit 2 (ease of handling the previous lens) for the 108 study subjects (excluding one who did not complete the questionnaire) was 0.0 (1.0). The median (interquartile range) of 0.0 (1.0) was not larger than that of the previous lenses, so the overall evaluation score for the ease of handling of the study lenses did not prove superiority over the previous lenses. Subgroup analysis also showed that the overall rating score for ease of handling of the study lens did not prove superiority compared to any of the previous lenses. |

The study lens was superior in the following endpoints. (1) The overall evaluation score for near vision of the study lens was superior to that of the previous lenses. (2) As a result of the relative comparison between the study lens and the previous lens, the study lens was found to be superior in overall comparison of lenses by VAS, wearing feeling, distance/mid-distance/near vision, and overall vision. |
