Combined surgery in PDVR
Jerzy Nawrocki, Slawomir Cisiecki (Lodz)
Aim: To present the results, surgical technique, complications
and induced astigmatism
after combined procedures, cataract removal, intraocular lens implantation
and pars plana vitreous surgery for proliferative diabetic retinopathy.
Material and Methods: 85 combined procedures of cataract
removal and vitreous surgery are analysed, Surgically induced astigmatism
was analysed in
25 consecutive eyes according to the vector analysis method presented
by Naylor and Jaffe. Mean follow-up was 8,4 months. Indications for
vitreous surgery
were vitreous haemmorhage with or without retinal detachment. 85 intraocular
lennses were implanted
into the capsular bag. All patients had cataract preoperatively.
Results: Postoperitavely best corrected visual acuity was improved
in more than 80 % of eyes. Postoperative complications were as follows:
fibrinous reaction in the anterior chamber and posterior synechiae,
repeated vitreous haemmorhage, neovascularisation
glaucoma, posterior capsule opacification; difference in surgically
induced astigmatism was not
statistically significant.
Conclusions: Our results support the data that combined surgery with
cataract removal, intraocular lens implantation and pars plana vitrectomy
for proliferative diabetic retinopathy is a safe procedure. Surgically
induced astigmatism is not statistically
different from divided procedures.
