We compared near vision, distance vision, distance corrected near vision in these three types of lenses on day 15 (±3) post-surgery.RESULTSAbout 69% of the eyes in the Matrix Aurium group had good uncorrected distance vision post-surgery; the proportion was 48% and 57% in the AcrySof single piece and AcrySof IQ group (P=0.09). The proportion of eyes with good distance corrected near vision were 38%, 33%, and 15% in the Matrix Aurium, AcrySof single piece, and AcrySof IQ groups respectively (P=0.02). Similarly, The proportion with good “both near and distance vision” were 38%, 33%, and 15% in the Matrix Aurium, AcrySof single piece, and AcrySof IQ groups respectively (P=0.02). It was only the Matrix Aurium group which had significantly better both “distance and near vision” compared with the AcrySof IQ group (odds ratio: 5.87, 95% confidence intervals: 1.68 to 20.56).CONCLUSIONMatrix Aurium monofocal lenses may be a good option for those patients who desire to have a good near as well as distance vision post-surgery.展开更多

Posterior PHPV was treated with lensectomy,posterior vitrectomy,retinal photocoagulation,and IOL implantation or silicone oil tamponade. Visual acuity(VA),pattern visual evoked potential(P-VEP),anatomic recovery,postoperative complications,and amblyopia outcome were examined.Subjects were followed-up for 3-48 mo after surgery.RESULTS:Of the 30 patients(33 eyes)with congenital cataract and PHPV included(average age,39.30±35.47mo),9 eyes had anterior PHPV and 24 had posterior PHPV. Thirty-two eyes were surgically treated. Eyes with anterior PHPV received an IOL during one-stage(6 eyes)and twostage(3 eyes)implantation. Postoperative complications included retinal detachment(1 eye)and recurrent anterior chamber hemorrhage(1 eye). In eyes with posterior PHPV,6 and 11 eyes received IOLs in one-and two-stage procedures,respectively. Silicone oil was retained in 2 eyes,and IOLs were not implanted in 4 eyes. VA significantly improved in 25 eyes following operations and 3-48 mo of amblyopia treatment. P-VEP P_(100) was improved following surgery in both PHPV types.CONCLUSION:Our surgical strategies are appropriate and effective for anterior and posterior PHPV. Early surgical intervention and amblyopia therapy result in positive treatment outcomes.展开更多
