A child suffering from traumatic cataract and corneal astigmatism of 2.14 D had a phacoemulsification operation and implantation of a ReSTOR Toric intraocular lens (IOL) to correct the astigmatism. The primary outcome measurements were the uncorrected distance visual acuity (UDVA), uncorrected near vision at 40 cm, intraocular pressure, spherical equivalent refraction, residual astigmatism, corneal astigmatism, presence of unusual optical phenomena, and use of spectacles. At 7 months postoperatively, UDVA was maintained between 16/20 and 24/20, near vision was between J1 and J3, residual spherical refraction was 0–0.37 D, and residual refractive cylinder was between 0 and 0.67 D. A multifocal toric IOL can provide the possibility of satisfactory vision for both distant and near conditions without the use of spectacles to meet children’s needs when studying and doing sports. Additionally, binocular vision can be reconstructed. This intervention, therefore, seems to be a satisfactory alternative.
Aim: To compare the integrity, roundness and diameter of the capsulotomy in the white cataract between femtosecond laser assisted capsulotomy and high-frequency capsulorhexis.Methods: The prospective study included 32 patients with white-nuclear cataracts, 16 of whom underwent femtosecond capsulorhexis and another 16 underwent diathermic high-frequency capsulorhexis. The integrity roundness and diameter of the capsulorhexis post-operation were compared.Results: Femtosecond group obtained 6 cases(37.5%)of complete capsular. No anterior capsule tear occurred. Diathermy high-frequency achieved continuous complete capsulor in 3 eyes(18.75%) and anterior capsule was teared in 13 eyes(81.25%). The femtosecond group has a mean capsular diameter of 5.4 mm, and the diathermic high-frequency group has an average capsular diameter of 6 mm. No posterior capsule tear occurred in both surgical procedures. Conclusions: Femtosecond laser-assisted cataract surgery can achieve high capsulor integrity and stable capsulorhexis diameter. Compared with the diathermic high-frequency capsulorhexis, the frequency of injecting the viscoelastic agent was reduced, and the tear of the capsule was less likely to occur. The continuous complete capsular(CCC) by femtosecond laser is more round, more complete ,more controllable and smoother than diathermy high-frequency(DHC).
ObjectiveTo observe the treatment effects of chop hook-assisted phacoemulsification surgery in patients with crystalline lens dislocation.MethodsThirty-seven eyes with cataracts and crystalline lens dislocations underwent cataract surgery. An L-shaped chop hook was introduced into the anterior chamber, and the tip was pushed or pulled to the centre of the anterior capsular edge of the zonular dialysis during the cataract operation. Postoperative follow-up was conducted for ≥ 1 month.ResultsAll patients’ postoperative visual abilities improved except one patient with glaucoma. One patient who underwent −5D intraocular lens implantation exhibited vision of 1/50. Visual acuity was less than 6/20 in 6 eyes, 6/20 to 10/20 in 7 eyes, and greater than 10/20 in 22 eyes.Conclusions
L-shaped chop hooks can be used to push or pull the anterior capsular edge of the zonular dialysis for protection and avoidance of further zonular damage. This strategy provides satisfactory effects and reduces use of additional instruments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
