Abstract Details

Purpose:

To document the visual outcome and efficacy of sulcus positioned extra focus pinhole IOL (Morchers GMBH) in a case of traumatic mydriasis with full 8.0 mm dilated pupil and irregular astigmatism post cataract surgery.

Setting:

Cleveland clinic Abu Dhabi

Methods:

extra focus pinhole IOL was implanted in sulcus having a pinhole aperture of 1.36 mm in a case of traumatic mydriasis preoperative pupil measurement 7.0 mm and irregular corneal astigmatism of 1.8 dpt post cataract surgery elsewhere with intraocular lens in the bag.

Results:

Left eye preoperative uncorrected distance visual acuity was 20/150. intermediate visual acuity was 20/100 and uncorrected near visual acuity wasJ10preoperative total corneal higher-order aberrations were 3.30 microns in left eye.total corneal coma was 0.97 µ. right eye was normal, 20/20. postoperative left eye uncorrected distance visual acuity was 20/25 intermediate uncorrected visual acuity was 20/25. and uncorrected near visual acuity was J3. binocular uncorrected distance visual acuity was 20/20. binocular intermediate uncorrected visual acuity was 20/20. and binocular near uncorrected visual acuity was J1 . postoperatively the glare and photophobia resolved completely. subjectively patient was satisfied with the visual outcomes

Conclusions:

Pinhole IOLs are an exciting armamentarium in cases of irregular astigmatism irregular and mydriatic pupils. They increase the depth of focus thereby giving a reasonably good visual acuity for distance intermediate and near. They are important tool when managing complex anterior segment problems and irregular corneas with high aberrations.
