Abstract Details

Purpose:

To Present Clinical Data of Distance ,Intermediate & near visual outcomes ,contrast Sensitivity, defocus curve, Photic Phenomena after Implantation of a new non-diffractive Extended Vision intraocular lens (Tecnis eyhance ICBOO IOL),in comparison with the Standard Monofocal IOL (Tecnis ZCBOO) IOL in Indian Population.

Setting:

Kashyap Memorial Eye Hospital Pvt. Ltd, Ranchi, Jharkhand, India.

Methods:

This prospective , non randomized and comparative Study included 100 patients scheduled to undergo cataract surgery with bilateral implantation of two monofocal IOLS Gr-1 New monofocal IOLs (100eyes) Tecnis Eyhance ICBOO & Gr-2 Standard monofocal IOLs (100eyes) (Tecnis ZCBOO) Binocular Un corrected Distance (UDVA), Intermediate (UIVA)66cm & near (UNVA) 40cm visual acuities , .Photopic & Mesopic contrast sensitivity, Dysphotopsia profile Halos ,glare & Starbursts(QoV,McAlinden), defocus curve & Spectacles dependence questionnaires were assessed at 90 post operative days after 2nd eye IOL implantation.

Results:

UDVA Mean±SD 0.09±0.12 & 0.04±0.50 for Gr-1&Gr-2,Non sig p=0.283,95%CI =0.01,0.08, UIVA Mean±SD 0.25±0.54 & 0.50±0.21 for Gr-1 & Gr-2,Sig (p=0.000),95% CI-.32,-.19,UNVA Mean±SD 0.45±0.20 ,0.51±0.13 for Gr-1 & Gr-2, Non Sig p value=0.06, 95% CI-.14..003.Photopic CS Non sig 5CPD (Diff=-.01, p= 0.62, 95%CI=-0.01,.0167 10CPD (p=0.86 ,95%CI=-0.016,0.019),For 15 CPD (p=0.69,95%CI=-0.014,0.021)-90 days ,Mesopic CS Non sig between GR-I & Gr-2 at 5CPD p=0.66,95%CI=-0.014,0.022,10CPD(p=0.72,95%CI=- 0.014,0.020) &15 CPD(P=0.59,95%CI=-0.026,0.046)-90 days. Defocus Curve sig better in Gr-1 at 1.00D,1.50D&2.00D p<.05 Intermediate Spectacles independence sig better Gr-1 P=0.00,Dysphotopsia are Comparable

Conclusions:

Bilateral implantation of non-diffractive extended vision IOL provided extended range vision,while maintaining low incidence of unwanted photic phenomena.Eyhance ICBOO IOLs specially beneficial to self driving computer working Indian population as well for shopping time label reading,seeing uneven surfaces while walking
