ABSTRACT
@#AIM: To evaluate the methods and effects of secondary intraocular lens implantation based on proliferative membrane in anterior segment reconstruction.<p>METHODS: Totally 156 eyes with penetrating injury had varying degrees of anterior segment disorders which had secondary intraocular lens implantation based on proliferative membrane to anterior segment reconstruction. Including partial penetrating keratoplasty, front-adhesion release, iris root suture, post-adhesion release, pupillary plasty, hole making in pupil area proliferative membrane and secondary intraocular lens implantation based on proliferative membrane. All patients were followed up 3-18mo.<p>RESULTS: The surgeries were successful in all patients. The corrected visual acuity of 123 eyes(78.8%)were ≥0.5, 17 eyes(10.9%)were ≥0.8 and 33 eyes(21.2%)were ≤0.4. Postoperative intraocular lens position was 133 eyes(85.3%), intraocular lens slightly off the center of 23 eyes(14.7%). Anterior chamber hemorrhage occurred in 8 eyes, 6 of them were recovered by conservative treatment and the blood membrane in another 2 eyes were sucked out through primary incision, and 5 cases of corneal plaque dense in the center of the cornea are partially penetrating keratoplasty. After 2mo, a rejection reaction occurs, which is cured by conservative treatment. All patients had slight postoperative inflammation and without severe long-term complications.<p>CONCLUSION: Reconstruction of the anterior segment of the eye, proliferative membrane can support the intraocular lens at the pre-implantation of the intraocular lens, without the need for suture fixation, thus avoiding various complications due to sutures.
ABSTRACT
AIM: To evaluate the use of 23G minimally invasive vitreous cutting system in the first stage of anterior segment reconstruction on severe ocular injury. METHODS: Fifteen patients with ocular injuries including the corneal and scleral rupture associated hyphema, vitreous hernia in anterior chamber, traumatic lens rupture, lens subluxation, applied 23G minimally invasive vitreous cutting system in the first stage of anterior segment reconstruction. RESULTS: The anterior ocular media of early postoperative became transparent quickly. No exudative lemma and no complications were found relate to puncture incisions after operations. CONCLUSION:23G minimally invasive vitreous cutting system can be used in the first stage of anterior segment reconstruction on sever ocular injury. It can reduce iatrogenic injury, operative complications and inflammatory response, also can shorten therapeutic time and create favorable conditions.
ABSTRACT
Objective To eveluate the methods and effects of multiple combined surgery anterior segment reconstruction and secondary posterior chamber intraocular lens implantation. Methods Secondary intraocular lens implantation combined anterior segment was reconstructed in 43 aphakias with different anterior segment disorders. Anterior segment reconstruction included:synechotomy, reposition of iridodialysis, pupil reformation, membranctomy in the pupil erea,anterior vitrectomy. Results The surgery was successful in all patients. The patients were followed up in 6-12 months.The postoperative visual acuities in 36 eyes were ≥0. 3(83. 7% ) and round pupil in 33 eyes (76. 7 % ). No severe complications happened. Conclusion It can have better effect to perform of anterior segment reconstruction and secondary posterior chamber intraocular lens implantation in different conditions with surgeryskill and better equipment.
