Abstract
BackgroundTo report the clinical outcomes of correcting pseudophakic ametropia using toric implantable collamer lens with a 360 um central hole (TICL V4c).Case presentationThe right eye of a 22-year-old male patient developed high myopia after unilateral phacoemulsification and intraocular lens (IOL) implantation following traumatic cataract 16 years ago. The manifest refraction was -11.50 DS/-2.50 DC × 175 with an uncorrected distance visual acuity (UDVA) of 20/2000 and a corrected distance visual acuity (CDVA) of 20/20. The manifest refraction of left eye was -6.25 DS/-3.75 DC × 180 with UDVA 20/200 and CDVA 20/20. Both eyes were implanted posterior chamber TICL V4c lens. Postoperatively, the refractive errors were +1.00 DS/-0.50 DC × 50 with UDVA 20/16 and CDVA 20/16 in the right eye and +0.75 DS/-0.75 DC × 45 with UDVA 20/16 and CDVA 20/13 in the left eye, respectively. No complications were observed.ConclusionsTICL V4c is safe, effective and predictable in managing pseudophakic ametropia.
Highlights
To report the clinical outcomes of correcting pseudophakic ametropia using toric implantable collamer lens with a 360 um central hole (TICL V4c).Case presentation: The right eye of a 22-year-old male patient developed high myopia after unilateral phacoemulsification and intraocular lens (IOL) implantation following traumatic cataract 16 years ago
In cases of higher refractive errors, the new posterior chamber implantable collamer lens (ICL V4c) provides an alternative approach, as corneal thickness may not meet the requirements of large refractive corrections
This study investigates the clinical outcomes of correcting high myopia of a young adult in the management of pseudophakic ametropia using Toric implantable collamer lens (TICL) V4c
Summary
To report the clinical outcomes of correcting pseudophakic ametropia using toric implantable collamer lens with a 360 um central hole (TICL V4c).Case presentation: The right eye of a 22-year-old male patient developed high myopia after unilateral phacoemulsification and intraocular lens (IOL) implantation following traumatic cataract 16 years ago. To report the clinical outcomes of correcting pseudophakic ametropia using toric implantable collamer lens with a 360 um central hole (TICL V4c). The manifest refraction of left eye was -6.25 DS/-3.75 DC × 180 with UDVA 20/200 and CDVA 20/20. Both eyes were implanted posterior chamber TICL V4c lens. Pseudophakic ametropia can be corrected by spectacles, contact lenses, intraocular lens (IOL) supplementation or exchange [1, 2], and corneal refractive surgeries [3, 4]. In cases of higher refractive errors, the new posterior chamber implantable collamer lens (ICL V4c) provides an alternative approach, as corneal thickness may not meet the requirements of large refractive corrections. The new 360 μm central hole design of ICL V4c allows for the natural flow of aqueous humor
