“…The sequential procedure seems to be more accurate for the calculation of the IOL power when compared with the triple procedure (cataract surgery, IOL implantation, and PK). Conversely, the triple procedure allows a faster visual rehabilitation, although it might have a higher risk of intra- and postoperative intraocular infections and other complications [ 2 , 19 , 20 , 22 ]. The longer duration of the open-sky state and a higher risk to the patient (including changes in intraocular pressure, posterior capsule rupture, prolapse of the vitreous body, and potential choroidal haemorrhage) frequently forces a need to divide the surgery into two separate approaches [ 2 ].…”

“…Lens injury with cataract formation frequently occurs in ocular trauma, intraocular inflammations, and after previous complicated surgeries. A typical triple procedure, consisting of PK, cataract extraction, and IOL implantation, leads to faster visual acuity improvement when compared with staged surgery, and it avoids successive surgeries [ 1 , 2 ]. Conversely, the large refractive errors associated with triple procedures also need to be taken into account [ 3 ].…”

Aim To conduct a retrospective analysis of secondary IOL implantation in patients who underwent PK with no simultaneous IOL implantation. Materials and Methods The retrospective study of the secondary implantation of IOLs was conducted in 46 eyes that underwent a primary operation with PK and cataract/lens extraction with no IOL implantation due to capsule rupture or combining corneal or intraocular complications. The minimum period from PK was 12 months. All secondary IOL implantations were performed from January 2011 to August 2017. Aphakic postkeratoplasty patients were treated using one of the surgical techniques for secondary IOL implantation. In-the-bag IOL implantation was possible if the posterior capsule was complete. If the lens capsule remnants were sufficient to provide secure IOL support, an in-the-sulcus IOL implantation was performed. Scleral fixation was offered in eyes with extensive capsular deficiency or the presence of the vitreous body in anterior chamber. BCVA and expected and achieved refraction were evaluated; we included using two biometry devices, and results were compared. Results The corrected distance visual acuity (CDVA) before surgery ranged from 0.1 to 0.8 (mean 0.54 ± 0.17). After secondary IOL implantation, CDVA ranged from 0.2 to 0.8 (mean 0.43 ± 0.14) at postoperative 1 month and from 0.3 to 0.9 (mean 0.55 ± 0.15) at postoperative 6 months (p < 0.05). Comparison of the final refraction using two methods of biometry showed no statistically significant difference in the group that underwent scleral fixation of the IOL, similar to the findings for the in-the-bag and in-the-sulcus IOL implantation groups. In the scleral-fixation group, p=0.55 for the USG biometry technique and p=0.22 for the OB technique. p values for the IOL-implantation group were p=0.49 and p=0.44, respectively. Conclusion Both implantation methods are safe for the patients. Final refraction is depending on the technique and indication to keratoplasty. Both biometry techniques deliver precise data for IOL choice.

“…Routine cataract surgery takes approximately 15 min to perform, and triple surgery, including cataract extraction, intraocular lens implantation, and keratoplasty performed continuously, takes approximately 60 min [ 5 ]. When cataract and vitreous surgery are performed continuously, the procedure takes at least 120 min [ 6 , 7 ].…”

Quantitative Assessment of Ophthalmic Viscosurgical Devices on Visibility, Spreadability, and Durability as Corneal Wetting Agents for the Wet Shell Technique

Purpose: To evaluate ophthalmic viscosurgical devices (OVDs) as corneal wetting agents for the wet shell technique, a common procedure in Japan to maintain the wettability of corneal surfaces. Methods: We surveyed Japanese ophthalmologists to determine the current state of the wet shell technique. After developing three ex vivo testing methods, we evaluated the corneal wetting properties of OVDs including 3% hyaluronic acid (HA) solution and OVD products, Opegan, Opelead, Viscoat, Shellgan, Discovisc, and Opegan-Hi. Results: Overall, 214 ophthalmologists (70%) had performed the wet shell technique, and Digital Features To view digital features for this article go to

“…Anterior segment surgeries in which cohesive 1% HA formulations are indicated include cataract surgery, intraocular lens implantation, and penetrating keratoplasty 8. Routine cataract surgery takes approximately 15 mins, while triple surgery, in which cataract extraction, intraocular lens implantation, and keratoplasty are performed simultaneously, has been reported to take approximately 60 mins 9. Moreover, when cataract surgery and vitreous surgery are performed simultaneously, it has been reported to take 120 mins or longer in several cases 10,11.…”

PurposeTo evaluate the effects of D-sorbitol addition on changes in the extrusion force of ophthalmic viscosurgical devices (OVDs).MethodsOVD formulations; the mixtures of 3% hyaluronic acid (HA) and 4% chondroitin sulfate (CS) containing 0%, 0.5%, or 1.0% D-sorbitol were prepared. Each prefilled syringe of OVD was stored at room temperature for 0, 15, 30, 60, or 120 mins after a small amount of viscoelastic agent was discharged from the needle. The extrusion force values (kgf) of these OVDs when reused after storage were measured with a texture analyzer. Moreover, 10 healthy adults (5 men and 5 women) used a pinch sensor to measure the extrusion force values for the HA/CS combination without D-sorbitol which was stored in the above manner, and used a 4-step scale to score the usability of OVD.ResultsFor the HA/CS combination without D-sorbitol, the extrusion force value was increased from its initial value (storage duration, 0 min) as storage duration increased. However, for the HA/CS combination containing 0.5% or 1.0% D-sorbitol, this value remained almost unchanged over time. Likewise, the pinch sensor-determined extrusion force values of HA/CS combination without D-sorbitol increased, depending on storage duration.ConclusionThe addition of D-sorbitol to viscoelastic agent may suppress the needle clogging that occurs with OVD storage, and may improve the usability of OVDs during surgery.
