Our study was performed to investigate the operative effects of pediatric cataract surgery with anterior vitrectomy. The study comprised of 38 pediatric patients aged 2-5 years and involved a total of 60 eyes with congenital cataracts. The study was done between March 2004 and December 2005. Posterior capsulorhexis with anterior vitrectomy was performed on 34 eyes of 20 children, and cataract extraction was performed on 26 eyes of 18 children. The percentages of various complications and rate of neodymium YAG (Nd:YAG) laser capsulotomy were followed up for 12-36 months. There were significant differences in the percentages of posterior capsule opacification (PCO) and rate of neodymium YAG (Nd:YAG) capsulotomy between the anterior vitrectomy group and cataract extraction group (P < 0.01). The anterior vitrectomy group was associated with less posterior capsular opacification (11.8%) than the cataract extraction group (76.9%). The YAG capsulotomy rate was 2.9% for the anterior vitrectomy group, and 57.7% for the cataract extraction group. After operation the fibrous exudates in anterior chamber and the intraocular lens subluxation or capture were 5.9% and 2.9% for the anterior vitrectomy group while for the cataract extraction group they were 23.1% and 15.4%; the difference was statistically significant (P < 0.05). The results suggest that primary posterior capsulorhexis with anterior vitrectomy in pediatric cataract surgery who are between 2 and 5 years old is necessary and effective procedure with low PCO rate.

“…Primary PCCC was first reported by Castaneda et al 10 in 1992, and has now become a primary procedure in pediatric cataract surgery. [11][12][13] Moreover, surgeons are increasingly introducing this procedure in cataract surgery for adult patients, and many reports have been published with good clinical results since 2003. [14][15][16][17][18] In this study, we applied the PCCC technique for diffractive IOL Implantation.…”

Primary posterior continuous curvilinear capsulorhexis combined with diffractive multifocal intraocular lens implantation M Ouchi AbstractPurpose To evaluate the effect of mild posterior capsule opacity (PCO) on visual acuity (VA) in eyes implanted with a diffractive multifocal intraocular lens (IOL) compared with a monofocal IOL, and the effect of posterior continuous curvilinear capsulorhexis (PCCC) combined with diffractive multifocal IOL implantation. Methods For the initial evaluation, we compared charge-coupled device (CCD) camera photographs taken through both a monofocal IOL-loaded model eye and a diffractive IOL-loaded model eye under the conditions of both with and without an opaque filter for the simulation of mild PCO. The clinical evaluation involved 20 patients who underwent bilateral implantation of the same diffractive multifocal IOL. In all 20 cases, PCCC was performed in 1 eye (PCCC group) and not performed in the fellow eye (NCCC group). Postoperative clinical results were then compared between the two groups. Results The CCD photographs revealed that the diffractive IOL-loaded eye was more strongly affected by the simulated PCO than was the monofocal IOL-loaded eye. In the clinical setting, the PCCC group registered better results than NCCC group in distance and near VA, low-contrast VA, and contrast sensitivity testing. Conclusions Diffractive multifocal IOLs tend to be more influenced by mild PCO than do monofocal IOLs, and PCCC prior to IOL implantation can contribute to the avoidance of this effect.

“…PCCC is used frequently to prevent more severe PCO formation in children's eyes in combination with anterior vitrectomy or posterior optic capture. 12,13 However, PCCC is not a standard procedure for the surgical treatment of age-related cataracts. Despite the developments in IOL design and improvements in surgical techniques, PCO is still the most common complication of cataract surgery.…”

Purpose We aimed at evaluating the effects of posterior continuous curvilinear capsulorhexis (PCCC) on contrast sensitivity. Materials and methods In this prospective, randomized, bilateral clinical study, 40 eyes of 20 patients who underwent bilateral cataract surgery were included. The phacoemulsification machine, viscoelastic substances, surgical tools, and intraocular lenses (IOLs) were the same for both eyes. The only difference was that we conducted the PCCC procedure before IOL implantation to one of the eyes of the patients. The selection of the eye that underwent the PCCC procedure was decided randomly. Results The mean photopic contrast sensitivity values at spatial frequencies of 1.5, 3, 6, 12, and 18 cpd (cycles per degree) were 41.55, 59.90, 61.25, 32.35, and 9.75, respectively, and for the control group these values were 39. 05, 56.60, 57.95, 29.80, and 8.75, respectively. The mean mesopic contrast sensitivity values at special frequencies of 1.5, 3, 6, 12, and 18 cpd were 41.20, 54.75, 55.55, 31.70, and 9.00, respectively, and for the control group these values were 38.35, 51.70, 52.15, 30.05, and 8.00, respectively. The mean contrast sensitivity values of the eyes that underwent the PCCC procedure were slightly better than the fellow eyes at all spatial frequencies, but the difference was statistically insignificant (P40.05). Conclusions In early post-operative period, the PCCC procedure exerts some positive effects on contrast sensitivity although these effects are statistically insignificant.
