Abstract Details

Purpose:

The aim is to evaluate the visual, refractive and patient satisfaction outcomes after cataract surgery with implantation of a trifocal toric intraocular lenses in cases of high ametropia.

Setting:

Astrakhan State Medical University, Ophthalmological department "Astrakhan Clinical Hospital" of the Federal State Budgetary Institution of Health "South Environmental Medical Center of the Federal Medical and Biological Agency" of Russia

Methods:

Patients’ age – 50-63 years. All patients has high ametropia with astigmatizm. All patients underwent standard phacoemulsification with IOL implantation trifocal toric intraocular lenses, bifocally in 3 cases. Intraocularlens toric power and axiswere determinated with Barrett toric calculator. Evaluation methods were autorefractometry, visometry in defocused conditions, subjective questioning, contrast sensitivity research, volume research of accommodation, postoperative monocular uncorrected (UDVA) and corrected (CDVA) distance visual acuity, distance corrected intermediate visual acuity (DCIVA) at 100cm, distance corrected near visual acuity (DCNVA) at 40cm, refraction and patient satisfaction (NEI VFQ-25 questionnaire) were evaluated.

Results:

Postoperatively mean logMAR monocular UDVA, CDVA, DCIVA and DCNVA were 0,16+0,13; 0,04+0,08; 0,10+0,13,and 0,08+0,10 respectively. Overall, 65% and 88% of the eyes achieved a decimal DCIVA and DCNVA of >0,8 respectively. 71% and 94% of the eyesreached a cylinder <0,5D and <1,0D respectively, with a centroid of 0,40D at 175'. The mean postoperativespherical equivalent was -0,19 +0,38D with 77% of the eyes within +0,25D. The mean VFQ-25 score was 92,04+3,30. Answers to questionnaire questions showed satisfaction with the results of vision at different distances in all cases

Conclusions:

The trifocal intraocular lenses are effective and rather universal remedy of correction of an aphakia for today, provides effective restoration of visual function at distances from near to far after cataract surgery in eyes with high ametropia and significant corneal astigmatism. Associated with the visual outcomes are a good refractive predictability and patient satisfaction.
