This
study was done to evaluate the clinical outcomes of
transscleral fixation of a foldable intraocular lens (IOL) in
eyes that had pars plana lensectomy combined with pars plana
vitrectomy for severe vitreoretinal disease. The medical
records of 21 patients who had a transscleral fixation of a
foldable IOL after previous vitrectomy combined with
lensectomy for severe posterior segment pathology were
reviewed. The underlying vitreoretinal diseases were
complicated proliferative diabetic retinopathy (n=9),
proliferative vitreoretinopathy (n=5), traumatic retinal
detachment (n=3), intraocular foreign body (n=2), and uveitic
retinal detachment (n=2). The postoperative best
corrected visual acuity (BCVA) was compared with the
preoperative BCVA. Autorefractometry and keratometry
measurements and central endothelial cell counts were
evaluated 1 day preoperatively and 6 months postoperatively.
Results
showed the mean age of the patients was 54.5 years. The
preoperative aphakic period ranged from 2 to 22 months.
The visual acuity reached the preoperative BCVA by 2 months
after surgery and was better than the preoperative BCVA at 6
months (P = .006) and at the final visit (P=.003). Six
months postoperatively, the mean myopic shift by cycloplegic
autorefractometry was -1.0 diopter (D) and the mean scalar
shift in surgically induced keratometric cylinder, 1.0D. The
mean central corneal endothelial loss at 6 months was 6.7%
(range 2.4% to 22.2%). The vitreoretinal complications
were a transient vitreous hemorrhage and a reopened macular
hole that was reattached after fluid-gas exchange.
CONCLUSION:
Transscleral fixation of a foldable IOL was safe and led to
favorable visual outcomes in aphakic vitrecomized eyes with
previous severe vitreoretinal disease.
