Assessing Calculation Error, Visual Acuity, And Patient Satisfaction With The Precizon Presbyopic Nva Iol By Opthec

This study aims to compare the accuracy of 3rd-generation formulas (SRK/T, Holladay 1, Hoffer Q) with 4th-generation formulas (Haigis, Barrett Universal II Formula, Kane) for calculating outcomes with the Precizon Presbyopic NVA IOL by OPTHEC. The primary focus is to evaluate patient satisfaction and best-corrected visual acuity (BCVA) at the 12-month postoperative.

This study aims to compare the accuracy of 3rd-generation formulas (SRK/T, Holladay 1, Hoffer Q) with 4th-generation formulas (Haigis, Barrett Universal II Formula, Kane) for calculating outcomes with the Precizon Presbyopic NVA IOL by OPTHEC. The primary focus is to evaluate patient satisfaction and best-corrected visual acuity (BCVA) at the 12-month postoperative. The study was perforemd in Retina Eye Hospital in Warsaw.

A retrospective analysis was conducted on 62 eyes to assess the accuracy of intraocular lens (IOL) calculation and its impact on postoperative best-corrected visual acuity (BCVA). The study cohort consisted of eyes with an average axial length of 23.80 mm (range: 19.28 mm - 31.78 mm). Calculation error, represented as Predictive Error (PE), was determined for Precizon Presbyopic Non-Visual Acuity (NVA) IOL. Additionally, patient satisfaction was evaluated through a standardized questionnaire, and visual acuity measurements were recorded at the 12-month follow-up visit

In the evaluation of Precision Presbyopic Non-Visual Acuity Intraocular Lens implantation, SRK/T exhibited the highest precision (PE -0.29), with III and IV generation formulas yielding similar PE values: Holladay 1 (-0.31), Hoffer Q (-0.31), Haigis (-0.32), Kane (PE -0.35), and Barrett Universal Formula (PE -0.31). No significant statistical differences were found between the 3rd and 4th generation formulas. The mean postoperative spherical equivalent (SE) was -0.51 (Vis LogMar scale 0.07), with 95.2% achieving visual acuity below 0.21, and 4.8% falling within 0.3 to 0.5. Complete independence from glasses was reported by 81% of patients. Despite 73% experiencing glare and halos, these were well tolerated without significant complaints.

 In conclusion, our study comparing 3rd and 4th-generation formulas for Precizon Presbyopic NVA IOL calculations found no significant statistical differences, indicating both generations offer comparable accuracy in predicting outcomes. High rates of patient satisfaction and favorable postoperative visual acuity outcomes suggest the effectiveness of these formulas in presbyopic
