Abstract Objective This study aims to analyze and compare the postoperative ocular parameters of two different types of implantable contact lenses (ICLs) (for retinal detachment) to provide a clinical reference for vitreoretinal surgery. Methods From March 2016 to March 2021, 24 patients (24 eyes) with rhegmatogenous retinal detachment following ICL implantation at the Eye Center of Taizhou Central Hospital were recruited. Based on the different types of ICL, they were divided into the V4 type ICL implantation group (V4 type group) and v4C type ICL implantation group (v4C type group), with 12 cases (12 eyes) in each group. Both groups were treated with pars plana vitrectomy; differences in postoperative ocular complications between the two groups were compared. Results The postoperative uncorrected and best corrected visual acuity for both groups were significantly higher than those preoperatively (P < 0.001); the same applied to the intraocular pressures (P < 0.05). Fluctuation in intraocular pressure was higher in the V4 group than in the v4C group (P < 0.05). The arch height, measured using anterior segment optical coherence tomography on the first day after operation, was lower in the V4 group than in the v4C group (P < 0.05). There was also no significant difference between the two groups before and after the operation (P > 0.05). Conclusion For patients with V4 type ICL implantation and mesh removal, stimulation of the ciliary body and the risk factors for pupil block caused by ciliary muscle spasm should be reduced as much as possible during pars plana vitrectomy. If postoperative complications such as decreased arch height and increased intraocular pressure occur, the application of compound tropicamide eye drops is an effective method to activate the pupil.

Background/Aims: The benefits associated with transconjunctival sutureless vitrectomy techniques are continuing to be defined. The purpose of this study was to compare the incidence of extreme changes in day 1 intraocular pressure (IOP) following 23-gauge sutureless vitrectomy compared with conventional 20-gauge vitrectomy. Methods: Fifty consecutive 23-gauge and 50 consecutive 20-gauge cases were included; eyes with a history of previous vitreoretinal surgery were excluded. 23-gauge surgery was completed with passive fluid air exchange where no long acting tamponade was indicated. The surgery remained sutureless unless a leak was visible at the end of the procedure. Data were collected by retrospective case note review. Statistical analysis was carried out using Fisher’s exact and chi-square tests. Results: Twenty-two percent (11/50) of 23-gauge vitrectomies required suturing of one or more ports. On the first post-operative day hypotony (IOP<5mmHg) occurred in 1/50 eyes in the 20- and 23-gauge groups. Raised pressure (IOP>21mmHg) occurred in 30% (15/50) of eyes in the 20-gauge group and 8% (4/50) of eyes in the 23-gauge group; IOP>30mmHg only occurred in the 20-gauge group (3/50). Conclusion: Fluid air exchange following 23-gauge vitrectomy is associated with very low risk of day 1 hypotony. This predominantly sutureless technique appears to reduce the incidence and magnitude of early post-operative IOP elevation compared with conventional 20-gauge vitrectomy.

Background A retrospective study was conducted to evaluate the risk of increased intraocular pressure (IOP) following a temporary silicone oil (SO) tamponade and to study some parameters possibly involved in this hypertension. Methods Forty-four patients with retinal detachment complicated by proliferative vitreoretinopathy (PVR) were treated by vitreoretinal surgery and SO tamponade. One to 11 years after SO removal, they underwent full ophthalmic examination. All these patients had a healthy, non-operated, normotensive fellow eye. Results Six (14%) of 44 eyes had IOP higher than 20 mmHg. Five other eyes (11%) had their IOP controlled by beta blockers. Phakic and pseudophakic eyes had a very limited tendency to develop ocular hypertension and anyway responded well to beta blockers. Residual SO droplets in the eye after removal of the big bubble of SO disappeared exponentially with a mean disappearance time of three years. Eyes with residual SO were no more prone to ocular hypertension than those without (p>0.50). No association was found between IOP and duration of SO tamponade (r=0.13) or between IOP and flare (r=0.14). Conclusion This study suggests that the risk of developing ocular hypertension after a temporary SO tamponade is moderate. No satisfactory explanation could be found for this increase of IOP.
